What is the end behavior of the graph of the exponential function f(x)=b^x when 0
Answer:
(1) B. f(x)->0 as x->∞, f(x)->∞ as x->-∞
(2) D. [tex]f(x)= 2^{-x}+5[/tex]
Step-by-step explanation:
[tex]f(x) = b^x[/tex]. Given 0<b<1
'b' is between 0 and 1 so b should be a fraction
'b' is a fraction, so for positive value of x , the value of f(x) cannot be negative.
the graph of f(x) will goes close to 0 but it never cross x axis
So end behavior is f(x)->0 as x->∞
for negative values of x , the y value increases
So end behavior is f(x)->∞ as x->-∞
(2) f(x) = 2^x
When graph reflects across y axis, x becomes -x
so [tex]f(x)= 2^{-x}[/tex]
For translating up by 5 units we add 5 at the end
so [tex]f(x)= 2^{-x}+5[/tex]
When 0 < b < 1, the graph of the function f(x) = [tex]b^x[/tex] is decreasing. This means that the values of f(x) will get smaller and smaller as x gets larger and larger.
In the limit as x approaches positive infinity, f(x) will approach zero. On the other hand, in the limit as x approaches negative infinity, f(x) will approach positive infinity.
The correct answer is g(x) = 2*+5.
The function g(x) = 2*+5 reflects the graph of f(x) = 2x across the y-axis and translates it up 5 units.
The reflection across the y-axis is achieved by multiplying the function by -1.
The translation up 5 units is achieved by adding 5 to the function.
The graph of g(x) is also shifted up 5 units.

The population of a town increased by 15% in 2016, and decreased by 5% in 2017. If the population of the town was 60,000 in the beginning of 2016, then what was it at the end of 2017?
Answer:
The population at the end of 2017 is 65,550
Step-by-step explanation:
step 1; find the population at the end of 2016
if 60,000 increases by 15% therefore final % = 100 +15 =115%
Therefore 60,000 = 100%
? = 115%
by cross multiplication
={ (115 % x 60,000) /100} =69,000
Step 2: find the population at the end of 2017
if 69,000 decrease by 5% therefore the final% = 100 -5 =95%
Therefore 69000 = 100%
? = 95%
by cross multiplication
= 69000 x 95/100 = 65,550
A scanner can scan 40 pages in 4 minutes. At this rate, how many pages can its can in 2 minutes?
Answer:
20 pages
Step-by-step explanation:
2 minutes is 1/2 of 4 minutes.
By proportion number of pages he scans in 2 minutes = 1/2 * 40
= 20 pages
Final answer:
To calculate the number of pages a scanner can scan in 2 minutes, you divide the total pages scanned in 4 minutes by 4 to find the rate per minute, and then multiply by 2. The scanner can scan 20 pages in 2 minutes.
Explanation:
To find out how many pages a scanner can scan in 2 minutes if it can scan 40 pages in 4 minutes, we use proportion or unit rate since the scanning speed is constant. We start by determining how many pages are scanned in one minute. Since 40 pages are scanned in 4 minutes, we divide 40 by 4 to find the scanning speed per minute:
40 pages ÷ 4 minutes = 10 pages per minute.
Now we find out how many pages can be scanned in 2 minutes by multiplying the rate by the number of minutes:
10 pages per minute × 2 minutes = 20 pages.
Therefore, the scanner can scan 20 pages in 2 minutes at the given rate.
Joey's eyes are 5.5 feet above the ground. He sets a mirror on the ground so he can see the top of a nearby building. The mirror is 8 feet away from Joey and 130 feet away from the base of the building. Estimate the height of the building using similar triangles. Round the height to the nearest foot.
A. 89 ft
B. 189 ft
C. 715 ft
D. 1040 ft
Answer:
89 feet
Step-by-step explanation:
First of all, we will make a diagram to demonstrate the given scenario as shown in the attached picture.
Now we will use similar triangles to set the ratios as shown below to figure out the height of the building.
[tex]\frac{x}{130} =\frac{5.5}{8}[/tex]
Now we will solve for x from this equation by cross multiplying.
[tex]8x=130\cdot5.5[/tex]
[tex]8x=715[/tex]
[tex]x=89.375[/tex]
Therefore, height of the building is approximately 89 feet.

b) [tex]-a(x+1)^2(x-2)^2[/tex]
c) 4 at least (even degree could be 4, 6, 8, etc)
Step-by-step explanation:
A polynomial graph has several features we look for to determine the equations.
The zeros of the function are the x-intercepts. If the x-intercepts touch but do not cross then the intercepts have an even multiplicity like 2, 4, 6, etc. If the x-intercepts cross over then they have an odd multiplicity.Degree is the exponent or multiplicity of each zero. Therefore if we know the multiplicity of each zero we can add them together to find or make an educated guess for the degree of the entire polynomial.The shape of the graph tells us what type of polynomial. Odd degrees have a backwards S shape. Even degrees have a W shape. The shape can even tell us the if the equation has a positive or negative leading coefficient. Upside down W or an M shape is negative. While a sideways S shape is negative.In this graph, there are two real zeros: -1,2
We can write them in intercept or factored form as (x+1) and (x-2).
Because the graph never crosses the x-axis each has an even multiplicity of at least 2.
The graph is facing down and is an upside down W so is negative. [tex]-a(x+1)^2(x-2)^2[/tex]
This means the function has a degree of 4 or higher with the degree being even.

B. y - 7 = 4 ( x + 3 )
C. y + 7 = 4 ( x + 3)
D. y + 7 = 4x - 12
Answer:
The equation of this line is y - 7 = 4(x + 3)
Step-by-step explanation:
To find this, start with the base form of point-slope form.
y - y1 = m(x - x1)
Now put the slope in for m and the two coordinates in for (x1, y1).
y - 7 = 4(x + 3)
Final answer:
The equation in Point-Slope form for the given point ( -3,7) and slope 4 is B. y - 7 = 4 ( x + 3 ). (Option B)
Explanation:
The correct equation in Point-Slope form for the given point and slope, where the point is ( -3,7) and the slope is 4, can be written as y - y1 = m(x - x1), where m is the slope and (x1, y1) is the point through which the line passes. Substituting the given values, we obtain y - 7 = 4(x + 3).
Therefore, the correct equation in Point-Slope form is:
B. y - 7 = 4 ( x + 3 )

The rabbit population in a certain area is 200% of last years population.There are 1,100 rabbits this year.How many were there last year?
Answer:
550
Step-by-step explanation:
We can write a proportion to find the total amount using the information given. A proportion is two equivalent ratios set equal to each other. Since we know the population increased to 200% of last year and is 1,100.
[tex]\frac{200}{100}=\frac{1100}{y}[/tex]
We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.
200y=100(1100)
200y=110,000
y=550
There was 550 rabbits last year.
By applying percentages and division, we find that there were 550 rabbits last year, as this year's population of 1,100 rabbits is 200% or twice the amount of last year's.
Explanation:The rabbit population in a certain area is 200% of last year's population. This year, there are 1,100 rabbits. It means that 1,100 is double the population from last year because 200% is equal to 2 times the original number. To find the population of rabbits last year, we need to take this year's total and divide it by 2. So, 1,100 rabbits divided by 2 equals 550 rabbits. Therefore, last year, the population of rabbits was 550.
