Question

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

Answer 1

The missing value is 20

Explanation:

Answer 2

D

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..
