Question

Please help with a mathematics question

Answer 1

B

Explanation:

let y = f(x)

Rearrange making x th subject

y =
`(3x)/(2)` + 5 ( subtract 5 from both sides )

y - 5 =
`(3x)/(2)` ( multiply both sides by 2 )

2(y - 5) = 3x ( divide both sides by 3 )

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

Change y back into terms of x

`f^(-1)`(x) =
`(2(x-5))/(3)` → B
