Question

this is a multi - part item. at which roots does the graph cross the x - axis? choose two correct answers. - 4, 5, - 2, 0

Explanation:

When a graph crosses the x - axis at a root, the multiplicity of that root is odd. For the roots - 4 and - 2 (assuming their multiplicities are odd), the graph will cross the x - axis. The root 5 (with a hole, so not a root where the graph crosses) and 0 (if the behavior at 0 is such that it touches or has even multiplicity) are not correct. So the roots where the graph crosses the x - axis are - 4 and - 2.

Answer:

-4, -2
