@xiphoidx please help ?

Answer 3

@Tajar
it means the inverse
\[f^{-1}(x)\]

Answer 4

wait but how do i solve it ? ._.

Answer 5

you just have to make it the inverse of itself, switch the x and y values so x= (3y-4)/5 and now solve for y

Answer 6

4+5/3y ?

Answer 7

step 1: multiply to get rid of the denominator so 5x=3y-4
step 2: add 4 so 5x+4=3y
last divide by 3 so (5x+4)/3=y :)

Do you understand :)
