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) = 0.5x + 2

Step-by-step 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 )

$\frac{y+4}{2}$ = x

Change y back into terms of x with x = $f^{-1}$ (x)

$f^{-1}$ (x) = $\frac{x+4}{2}$ = 0.5x + 2
