You may need to label the given ordered pairs to correctly graph the inverse. Remember, if the given ordered pair is $(a, b),$ then the inverse is $(b, a).$

Q: What is the line of reflection used when graphing the inverse of a function?
A: y = x 

The line of reflection does not need to be graphed, but is a helpful reference.

Q: Is the given graph a function? Is the inverse a function? Explain.
A: The given graph and its inverse are both functions because they individually pass the vertical line test (VLT).
