Graphing Polynomial Functions Pre-Test

The graph touches the x-axis at x = -4 and crosses the x-axis at x = 1. : Which statement describes the graph of f(x) = -4x3 - 28x2 - 32x + 64?

The graph crosses the x-axis at x = 0 and touches the x-axis at x = -5. : Which statement describes the graph of f(x) = 4x7 + 40x6 + 100x5?

-5 with multiplicity 2 and 0 with multiplicity 4 : Which of the following describes the zeroes of the graph of f(x) = 3x6 + 30x5 + 75x4?

B : A polynomial function has a root of -4 with multiplicity 4, a root of -1 with multiplicity 3, and a root of 5 with multiplicity 6. If the function has a positive leading coefficient and is of odd degree, which could be the graph of the function?
