The correct response is:
The multiplicity of (x−3) is even because the graph of p(x) touches the x-axis at (3,0) and then turns around.
When a polynomial has a factor with even multiplicity, the graph touches the x-axis at that root but does not cross it; instead, it turns around. In contrast, if the multiplicity were odd, the graph would cross the x-axis at that point. Since the description of the curve indicates that the graph touches the x-axis at (3, 0) and then turns around, this indicates that the multiplicity of (x - 3) is indeed even.
