A polynomial function has a root of –7 with multiplicity 2, a root of –1 with multiplicity 1, a root of 2 with multiplicity 4, and a root of 4 with multiplicity 1. If the function has a positive leading coefficient and is of even degree, which statement about the graph is true? A. The graph of the function is positive on (2, 4). B. The graph of the function is negative on (4, positive infinity). C. The graph of the function is positive on (negative infinity, –7). D. The graph of the function is negative on (–7, –1).
