Question

Use the graph of each polynomial function to find the factored form of the related polynomial. Assume the polynomial has no constant factor.

What are the zeros of this function? (2 points) _______, _______
What is the factorization of the polynomial? (2 points)

Answer 1

• zeros: x = -2; x = +4
• factorization: y = (x +2)(x -4)

Explanation:

The zeros are where the graph crosses the x-axis (y=0). They are x=-2 and x=4.

The factors are the binomials that are zero when x has the value of a zero:

y = (x +2)(x -4)
