For each of the following functions:
(i) find f^-1 (x)
and the funtions are f(x) = (3 - 2x)/4

Answer 1

We need to inverse \[\frac{ 3-2x }{ 4}\]

Answer 5

I don't get that

Answer 6

replace f(x) with "y"
so its y = (3 - 2x)/4

Answer 7

and then switch x and y ....
so u will get
x = (3 - 2y)/4
and then solve for y

Answer 8

so for solving for y we do
