Question

PLEASE HELP

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).
Complete the inverse function for the function given below.

Answer 1

Answer: F -1(x) = 0.5 x + 2

Explanation:

Just took the test on edmentum and got a 100

Answer 2

`f^(-1)`(x) = 0.5x + 2

Explanation:

let y = f(x) and rearrange making x the subject , that is

y = 2x - 4 ( add 4 to both sides )

y + 4 = 2x ( divide both sides by 2 )

`(y+4)/(2)` = x

Change y back into terms of x with x =
`f^(-1)` (x)

`f^(-1)` (x) =
`(x+4)/(2)` = 0.5x + 2
