Inverse Functions (Algebraic Representation)

NOTES
1. Write your function, replacing f(x) with y
2. Solve for x
3. Switch the variables
4. Replace y with "f^-1(x)."


PROBLEM 1

PROBLEM 2

REFLECTION
I think inverse functions are easy, because you are solving an algebraic expression. The one thing I may forget to do, is to not change f(x) to y.
