Question

What is the inverse of the given relation? y = 4x - 8

Answer 1

First, switch x and y
x = 4y - 8
Then perform the opposite operations:
x + 8 = 4y

`(x)/(2) + (8)/(4) = y`

`(x)/(2) + 2 = y`

Answer 2

to inverse a equation make all y's x and andy x's y

Thus the inverse is
x=4y-8

Evaluated to
4y=x+8
y=
`(1)/(4)x +2`
