How to solve for x cubic function
WebUnlike quadratic functions, cubic functions will always have at least one real solution. They can have up to three. For example, the function x (x-1) (x+1) simplifies to x 3 -x. From the initial form of the function, however, we can see that this function will be equal to 0 when … Webof the cubic function is zero. The solutions of this equation are the x -values of the critical points and are given, using the quadratic formula, by The sign of the expression inside the square root determines the number of critical points.
