Question

9. Use the graph of each polynomial function to find the factored form of the related polynomial.

Assume the polynomial has no constant factor.
A
What are the zeros of this function? (2 points) (-1). 4
What is the factorization of the polynomial? (2 points)

Answer 1

A. What are the zeros of this function? (2 points)

-2, 4

What is the factorization of the polynomial? (2 points)

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

B.

What are the zeros of this function? (2 points)

2, 3

What is the factorization of the polynomial? (2 points)

y = (x - 2)(x - 3)

Explanation:

Answer 2

The zeros are the points on the x-axis where the graph intersects.

For factorization, you do (x - the zero) for each zero, and multiply them together.

7. A. The zeros are -2 and 4.

The factorization is (x + 2)(x - 4)

7 B. The zeros are 1 and 3.

The factorization is (x - 1)(x - 3)
