Given the function f(x)=4(x+3)-5, solve for the inverse function when x=3
--------------
Find the inverse function::
1st:: Interchange x and y to get:
x = 4(y+3)-5
2nd:: Solve for "y"::
4(y+3) = x+5
---
y = (x+5)/4 - 3 That is the inverse function
------------------------
Evaluate inverse function at x = 3
-----
y = 8/4 - 3 = -1
--------------------
