Step-by-step explanation:

To find

, (the inverse of the function) you need to first replace the f(x) with y...

Then switch the x and the y.

Solve for y.

Take the square root of each side...
a) 35w+55-10w = 25w+55
28w+75-5w+12 = 23w +87
b) 25w+55 + 23w +87
=48w+142
they will be short by 2(24w+71)
c) 50w+25 = 25(2w+1)
answer: =98w+167
i think
It just depends but usually it is an inverse for the original equation that you were given
