The effects of b and c on the graph are more complicated. In this live Gr 12 Maths show we take a look at Graphs of Cubic Functions. The graph of the cubic function Cx x3models the side length of a cube as the independent quantity and the volume of the cube as the dependent quantity.
In a cubic function the highest power over the x variable s is 3.
One more method to find out the cubic function is graphical. And so it is now going to look like this. All odd-degree polynomials have at least one real root. For the function of the form y a x h 3 k.
