Question

what's the inverse of y = 4x-2

Answer 1

find x in terms of y
then replace the y by x
- then you have the inverse

Answer 2

so would it be y=1/4x-1/2 ?

Answer 3

after adding 2, and dividing by 4, you are left with

(y + 2)/4 = x

if you replace x and y with each other now

(x+2)/4 = y

or simplified down to 1/2 + x/4 =y
