Answer
The graph represents a function.
Work Step by Step
RECALL:
(1) In a graph that represents a function, all vertical lines will pass through at most one point only (vertical line test).
(2) If a vertical line passes through the graph at more than one point, then the graph does not represent a function.
Notice that all vertical lines will pass through the graph one time at most.
This means that the graph does represents a function.
