Find g-1(x) when g(x)=3/5x-9

(x) =

Step-by-step explanation:

let y = g(x) and rearrange making x the subject

y = x - 9 ( add 9 to both sides )

y + 9 = x

Multiply both sides by 5 to clear the fraction

5y + 45 = 3x ( divide both sides by 3 )

= x

Change y back into terms of x, thus

(x) =

ik how do do this just give me a few minutes and i will give it to
