Asked by Jim
y=2x+3 How do you find the inverse of this function? I know that you have to get the x by itself but i am not sure how.

I do it this way:
1. switch the x and y variables to get
x = 2y + 3
2. solve this new equation for y
2y = x - 3
y = (1/2)x - 3/2
some people solve the original for x fist, then switch the variables.
-makes no difference, same number of steps, same work, same result.
