The horizontal line intersects the graph of the given function at more than one point, which means there exist two different inputs with the same output. Therefore, the function is not one-to-one. The horizontal line test states that if any horizontal line intersects a graph more than once, then the graph is not one-to-one. In this case, it is possible to draw a horizontal line that intersects the graph in two points, which means the function is not one-to-one.
