Answer:

d

Step-by-step explanation:

The red graph is an enlargement of the black graph.

Note coordinates of vertices of black graph to coordinates of red graph

(2, 2 ) → (2, 4 )

(4, - 2 ) → (4, - 4 )

(- 2, - 2 ) → (- 2, - 4 )

The y- coordinates of the red graph are twice the y- coordinates of the black graph.

and

\frac{y}{2} = f(x) ← multiply both sides by 2

y = 2f(x) ← as required, thus

equation of red graph is

\frac{y}{2} = f(x) → d

What is the inverse of the function?<br> f(x) = 1/3x-5
OlgaM077 [116]

Answer:

        -1

       f   (x) = -3(x + 5)

Step-by-step explanation:

1)  in f(x) = 1/3x-5, replace f(x)= with y= as follows:  y = (1/3)x - 5

2) interchange x and y, obtaining:  x = (1/3)y - 5

3) solve this result for y:  (1/3)y = -x - 5, or -(x + 5).  Next, multiply both sides by                        3 to eliminate the fraction (1/3):  y = -3(x + 5)

4)  replace y with the symbol for "inverse of f(x);

        -1

       f   (x) = -3(x + 5)
