How many extrema can a cubic function have
WebTesting for Relative Extrema in Cubic Function. Find all relative maximum and minimum points for the function f(x)= x3−x. f ( x) = x 3 − x. Solution Of course this example is made … WebA cubic function can have 1 real root (repeated 3 times, or 1 real root and 2 complex roots), 2 real roots (when one real root is repeated twice), or 3 distinct real roots. Of course, a cubic always has at least 1 real root – if we can find it, then we can factor the cubic into the product of a linear function and a quadratic function.
