Here are 5 follow-up questions you might explore:
- How can you verify that the inverse function you found is correct?
- What are the domain and range restrictions of each inverse function?
- Why do some inverse functions have restrictions on the domain that the original function did not?
- How does the process of finding an inverse change for functions involving square roots?
- Can every function have an inverse?
Tip: Always check if the function is one-to-one (i.e., passes the horizontal line test) before attempting to find the inverse.

y = (x - 5) / (x + 4)
y = 4(x - 5) + 3
y = 6√(x - 9)
y = (2x - 9)/x
y = (x - 5)/(x + 1)
