Example 1

Determine the function that models the table below:

polyextable

Step 1. Determine the zeros of the function.

(-5, 0), (1, 0), (3, 0)

Step 2. Turn each zero into a factor of the function.

Since x = -5, then (x + 5) is a factor of the polynomial.

Since x = 1, then (x - 1) is a factor of the polynomial.

Since x = 3, then (x - 3) is a factor of the polynomial.

Step 3. Determine the factored form of the polynomial.
