Kendra drew the graph g(x). she noticed it was possible to draw a horizontal line that intersected the graph at two points. what best describes what this means.

This means that the graph is most likely of a quadratic function or an absolute value function. Quadratic functions make parabolas (which look like a U) when graphed, and absolute value functions make V-shapes when graphed. So, a horizontal line could intersect either of these types of graphs at two places (as long as it's not at the vertex).

Any pictures or something i need more info
