Question

Which best describes a root of a polynomial?

A. A point on the graph of the polynomial that has a greater y-value than any nearby points on the graph B. The y-value of a point on the graph of the polynomial that has an x-value of 0.
C. The x-value of a point on the graph of the polynomial that has a y-value of 0.
D. A point on the graph of the polynomial that has a greater x-value than any nearby points on the graph.

Answer 1

I think the correct answer from the choices listed above is option C. A root of a polynomial is the x-value of a point on the graph of the polynomial that has a y-value of 0. Roots of a polynomial are the x-intercepts in the graph of the function given. Hope this answers the question.
