Graph 5 consists of line segments connecting the points (-7, 2), (-1, 0), and (3, -2). There is a hole at (-1, 0).
Step 2: Determine if the graph is a function
A graph represents a function if and only if every vertical line intersects the graph at most once. This is known as the vertical line test. Even with the hole at x=-1, no vertical lines intersect with two or more _points_ on this graph.
Step 3: Select Yes or No.
Because the graph passes the vertical line test, we can conclude that the graph represents a function.
