F(x)=9(x-8) find f^-1(x)

(x) = x + 8

Step-by-step explanation:

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

y = 9(x - 8) ← divide both sides by 9

= x - 8 ( add 8 to both sides )

+ 8 = x

Change y back into terms of x with x = (x) , thus

(x) = x + 8

question:

could we have options?

the answer is 0.071
