Question

The inverse of the function f(x) = 1/2x + 10 is shown.

h(x) = 2x – ?

What is the missing value?

Answer 1

The Answer is 20

Explanation:

if ya know ya know

Answer 2

We have to find the inverse of the function:
f ( x ) = 1/2 x + 10
y = 1/2 x + 10
- 1/2 x = - y + 10 / * ( - 1 )
1/2 x = y - 10 / * 2
x = 2 y - 20
f^(-1) ( x )= 2 x - 20
h ( x ) = 2 x - 20
Answer:
The missing value is 20.
