#### Answer

The given graph does not represent a one-to-one function.

#### Work Step by Step

RECALL: Horizontal Line Test
If all horizontal lines will pass through the graph of a function in at most one point, then the function is one-to-one.
Note that most of the horizontal lines that will pass through or touch the graph will do so at two points.
Thus, the given graph does not represent a one-to-one function.
