A cubic equation has the form ax 3 + bx 2 + cx + d = 0. Setting f(x) = 0 produces a cubic … you will get a structure that contains all that information. The solutions of this equation are called roots of the cubic function defined by the left-hand side of the equation. Find more … Graphing Cubic Functions. They are found by setting derivative of the cubic equation equal to zero obtaining: f ′(x) = 3ax2 + 2bx + c = 0. In a cubic equation, the highest exponent is 3, the equation has 3 solutions/roots, and the equation itself takes the form + + + =.While cubics look intimidating and can in fact be quite difficult to solve, using the right approach (and a good amount of foundational knowledge) can tame even the trickiest cubics. First, I'll point out that we've learned quite a bit about cubic functions over the past few lessons such as seen the variety of graphical forms and we've made use of the structure of the equation in both its expanded and its factored forms. Sign in to comment. The solutions of that equation are the critical points of the cubic … Cubic Function Match c Connect the Navigator computer to a data projector or Smart Board.
