WebNov 1, 2024 · Use the Factor Theorem to find the zeros of f(x) = x3 + 4x2 − 4x − 16 given that (x − 2) is a factor of the polynomial. Answer Use the Rational Zero Theorem to Find … WebThe zeros of a function f f correspond to the x x -intercepts of its graph. If f f has a zero of odd multiplicity, its graph will cross the x x -axis at that x x value. If f f has a zero of even multiplicity, its graph will touch the x x -axis at that point. If this is new to you, we recommend that you check out our zeros of polynomials article.
