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. WebA cubic function is a polynomial function of degree 3 and is of the form f (x) = ax 3 + bx 2 + cx + d, where a, b, c, and d are real numbers and a ≠ 0. The basic cubic function (which is also known as the parent cube function) is f (x) = x 3.
