Question

if f(g(x))=x and f(x)=3x-4,find g(x)

Answer 1

is it g(x)=x+4/3

Answer 2

i am going to assume G is the inverse function of F(x)
so to find the inverse function

let f(x)= y

so you get
y=3x-4

to get the inverse function you want to make x the subject

add 4 to both sides

y+4=3x
divide by 3 on both sides

(y+4)/3=x

now let x=g(x)
let y=x

(x+4)/3=g(x)

Answer 3

so im right?
