What is the inverse function of #f(x) = 4x + 2#?

1 Answer

Mar 2, 2018

The inverse function is #y=(x-2)/4#.

Explanation:

First, lets rewrite the equation like this:

#y=4x+2#

In order to find the inverse of an equation, the easiest thing to do is to switch #x# and #y# and then isolate #y#:

#x=4y+2#

#4y=x-2#

#y=(x-2)/4#
