Cubic Graphs Examples

When a cubic function is mapped on a Graph is forms an "S" shape. Cubic functions will have up to three real solutions. "Solutions" are the the points where the cubic curve meet, or "cut", the x-axis. The x-axis is the horizontal axis and horiztonal can be remembered as flat like the word "horizon". Cubic graphs can intercept the x-axis once, twice or three times. The graph of the cubic y = x3 is shown below.
Cubic Graph Worksheet Example
The graphs of the cubics; y = x3 + x2 - 1, y = x3 - 3x2 + 2 and y = -x3 - 2x2 are shown below:

How To Interpret Cubic Graphs

Cubic functions can sometimes be factorised but it is not usually easy or simple to do so. Here, these worksheets help us to solve the unknown values of a cubic function by using a graph.
