Answer:

Step-by-step explanation:
To obtain the inverse of f(x)
let y = f(x) and rearrange making x the subject, that is
y = 2x - 1 ( add 1 to both sides )
y + 1 = 2x ( divide both sides by 2 )
= x
Change y back into terms of x with x =
(x) , thus
(x) = 
Evaluate g(3) and substitute the value obtained into
(x)
g(3) = 3² + 1 = 9 + 1 = 10, then
(10) =
= 
4+2=6 then you bring the 6 to the other side so you have combine like terms. 6-6=0 so its 0
