The inverse of the function f (x) = {x+

+ 10 is shown

h (x) = 2x-0

What is the missing value?

A. 1

B. 5

C. 10

D. 20

D

Step-by-step explanation:

f (x) = x + 10

Replace f (x) with y.

y = x + 10

Now, remember that in an inverse function you flip the x and y, so

x = y + 10

Solve for y

y = x - 10

because its 2x ... we must multiply by 2.

2y = 2x - 20

Original equation:

h (x) = 2x - 0

h (x) is 2y ...

D.

The missing value is 20
