Question

What is a root of a polynomial function?

Answer 1

D.A value of the variable that makes the polynomial equal to zero

Explanation:

Answer 2

See below.

Explanation:

The solutions (also called zeros and x-intercepts) are the roots of the equation. The factored from of a polynomial can be found from the zeros or x-intercepts of the graph.

If the x-intercepts or roots are x= 1 and x= 7, then the factors are x-1 and x-7.

So the factored form is (x-1)(x-7).
