Which of the following best describes how you can determine the x-intercepts of a polynomial function without graphing?

Question

a. Find the number of terms of the polynomial function
b. Find the value of the function when x equals zero
c. Find the zeros of the polynomial function
d. Find the degree of the polynomial function

Answer 1

The best way to determine the x-intercepts of a polynomial function without graphing is:

c. Find the zeros of the polynomial function

The x-intercepts of a polynomial occur where the function equals zero, which is equivalent to finding the zeros (or roots) of the polynomial.
