Question

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?

Answer 1

The graph of the function is positive on (-∞ –7).

Explanation:

Answer 2

Answer: the graph of the function is positive on ( -infinity, -7)

Reason: f(-8)= 840,000a
840,000a is a positive number
