Section 4.1

Polynomial Functions and Models

Find a polynomial of degree 3 whose zeros are -4, -2, and 3.

Use a graphing utility to verify your result.

For the polynomial, list all zeros and their multiplicities.

2 is a zero of multiplicity 1 because the exponent on the factor x – 2 is 1.

–1 is a zero of multiplicity 3 because the exponent on the factor x + 1 is 3.

3 is a zero of multiplicity 4 because the exponent on the factor x – 3 is 4.
