Question

the x-values where a polynomials value is zero, representing where the graph crosses the x-axis, are called ____. the point where the polynomial graph intersects the y-axis, equivalent to the polynomial’s value when ( x = 0 ), is known as the ____.

Explanation:

1. By definition, the x-values that make a polynomial equal to zero (where its graph crosses the x-axis) are called roots or zeros of the polynomial.
2. The point where a polynomial's graph intersects the y-axis occurs when x=0, and this point is formally called the y-intercept of the polynomial.

Answer:

1. roots (or zeros) of the polynomial
2. y-intercept of the polynomial
