If is a zero of the polynomial function, then is a factor of for the polynomial function.

If is the degree of the polynomial function, then raise the factor to the power.

The zeros of the polynomial function is .

Degree of the polynomial function is .

Since is a zero of the polynomial function, is a factor of the polynomial function.

Since the degree of the polynomial function is , raise to the fourth power.

Thus, the polynomial function is .

The polynomial function is .
