Draw the graphs of f(x) and g(x) on the same coordinate plane. Explain what about your graph shows that the functions are inverses of each other.

First correct answer will get 25 pts and brainliest!!!! So please help! :D

Answers

Answer 1
Part A:

Given that [tex]f(x)= \frac{1}{3} x+2[/tex], we find the inverse g(x) as follows:

First, we rewrite the function as: [tex]y=\frac{1}{3} x+2[/tex]

Next, we switch x and y and then solve for y as follows:

[tex]x=\frac{1}{3} y+2 \\ \\ \frac{1}{3} y=x-2 \\ \\ y=3(x-2) \\ \\ y=3x-6[/tex]

We then rewrite the equation using function notation to get:

[tex]g(x)=3x-6[/tex]



Part B:

For two function that are inverse of each other, the composition of the two functions gives x.

Thus,

[tex]f \circ g=f(g(x))=f(3x-6)= \frac{1}{3} (3x-6)+2=x-2+2=x \\ \\ g\circ f=g(f(x))=g( \frac{1}{3} x+2)=3( \frac{1}{3} x+2)-6=x+6-6=x \\ \\ \therefore f\circ g=g\circ f=x[/tex]

Since, f o g = g o f = x, hence g(x) is the inverse of f(x).



Part C:

The graphs of f(x) and g(x) are attached.

From the graph it can be seen that the prperties of both graphs are similar, the properties of one graph in the x-axis correspond to the properties of the other graph in the y-axis and vice-versa. Also, the two lines intersect at a point were x = y.

The community center has a pottery class each month. Each student pays $15 for the class and $27 for materials. This month the pottery class brought in a total of $714. How many students are in the class this month?

please answerrrrrr

Answers

If you add $15 + $27 because that's how much it costs for each student, you get $42. Then you divide $714 by $42, you get 17 and that's how many students are in the class this month.

Answer:

[tex]17[/tex]

Step-by-step explanation:

Let the number of students in pottery class be [tex]x[/tex]

Price each student pays for the class = [tex]\$15[/tex]

Price each student pays for the material = [tex]\$27[/tex]

Total earning of pottery class = [tex]\$714[/tex]

We can write this in expression as-

[tex]15x + 27x = 714[/tex]

Solving the expression we get[tex]15x + 27x = 714\\42x = 714\\x = \frac{714}{42} \\x = 17[/tex]

144 degrees is the measure of the interior angles of the polygon.

What is a polygon?

In Mathematics, a polygon can be defined as a two-dimensional geometric figure that consists of straight line segments and a finite number of sides. Additionally, some examples of a polygon include the following:

• Triangle

• Quadrilateral

• Pentagon

• Hexagon

• Heptagon

• Octagon

• Nonagon

Generally speaking, the measure of the angle at the center of a regular polygon is equal to 360 degrees. Therefore, the smallest angle of rotation that maps (carries) a regular polygon onto itself can be calculated by using this formula:

α = 360/n

The sum of the measures of the interior angles of an n-sided polygon is given by the formula:

S = (n - 2) × 180 degrees

So, for a 10-sided polygon, we have:

S = (10 - 2) × 180 = 8 × 180 = 1440 degrees

To find the measure of each interior angle, we divide the sum by the number of angles (which is the same as the number of sides for a polygon):

m = S/n = 1440/10 = 144 degrees

Therefore, each interior angle of a 10-sided polygon has a measure of 144 degrees.

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros.

1. 7, 1+i
2.

Answers

Final answer:

The polynomial function of least degree with rational coefficients, a leading coefficient of 1, and the given zeros 7, 1 + i, and 1 - i is f(x) = x^3 - 9x^2 + 21x - 14.

Explanation:

In mathematics, zeros are the x-values where a function touches or crosses the x-axis, or the values where f(x) = 0. When a polynomial has rational coefficients and you have a complex zero (a + bi), the conjugate of that zero (a - bi) also needs to be a zero of the polynomial. This is based on the Complex Conjugate Root Theorem. Hence, in this case, the other zero will be 1 - i.

Since you are given zeroes of 7, 1 + i, and 1 - i, the polynomial function of least degree is obtained by employing the Factor Theorem, which states that if k is a zero of a polynomial, then (x - k) is a factor of the polynomial.

Therefore, f(x) = (x - 7)(x - (1 + i))(x - (1 - i)) = (x - 7)(x^2 - 2x + 2). So, f(x) = x^3 - 9x^2 + 21x - 14 is the polynomial function of least degree with rational coefficients, a leading coefficient of 1, and the given zeros.

Its C
Final answer:

Stock B is worth more in 50 years, $1,575.84 more per share.

Explanation:

To determine which stock option is worth more in 50 years, we need to find the value of each stock after 50 years.

For Stock A, we have the equation: an = 15n + 130. Plugging in n = 50, we get a50 = 15(50) + 130 = $880.

For Stock B, we have the equation: an = 36(1.09)n - 1, where n is the number of years. Plugging in n = 50, we get a50 = 36(1.09)^50 - 1 = $2,455.84.

Therefore, Stock B is worth more in 50 years, $1,575.84 more per share.
