Question

I need help on this I am just going to use the picture

Answer 1

D is the correct answer

Answer 2

D

Explanation:

let y = f(x), that is

y =
`(2x-3)/(5)`

Rearrange making x the subject

Multiply both sides by 5

5y = 2x - 3 ( add 3 to both sides )

5y + 3 = 2x (divide both sides by 2 ) , then

x =
`(5y+3)/(2)`

Change y back into term of x, hence

`f^(-1)`(x) =
`(5x+3)/(2)` → D
