WebUsing Factoring to Find Zeros of Polynomial Functions. Recall that if f f is a polynomial function, the values of x x for which f (x) = 0 f (x) = 0 are called zeros of f. f. If the equation of the polynomial function can be factored, we can set each factor equal to … WebSolution. Always go back to the fact that the zeros of functions are the values of x when the function’s value is zero. We can see that when x = -1, y = 0 and when x = 1, y = 0 as well. Hence, the zeros of f (x) are -1 and 1. Example 2. The graph of f (x) is shown below.

WebThe multiplicity of a zero is important because it tells us how the graph of the polynomial will behave around the zero. For example, notice that the graph of f (x)= (x-1) (x-4)^2 f (x) = (x −1)(x −4)2 behaves differently around the zero 1 1 than around the zero 4 4, which is a …
