Answer

This is not a graph of a function.

Work Step by Step

Apply the vertical line test: If it is possible for a vertical line to cross a graph more than once, then the graph is not the graph of a function. --- The y-axis is a vertical line, and it crosses the graph twice, so the graph fails the vertical line test. This is not a graph of a function.
