Question

Approximate the real number solution(s) to the polynomial function f(x) = x3 − 4x2 + x + 6.

A. x = −3, x = −1, x = 2
B. x = 3, x = 1, x = −2
C. x = 3, x = −1, x = 2
D. x = −3, x = 1, x = −2

Answer 1

C is the answer. Solutions to a polynomial are numbers that, when plugged into the equation, make the equation equal zero

So if you plug 3, -1, or 2 into x^3 - 4x^2 + x + 6, it will equal zero.
