**1. How can you tell whether a graph is a cubic shape or not?**

If the equation of the function has an x

^{3}term it will have a cubic-shaped graph.

**2. How many points need to be plotted to draw the graph of a cubic function?**

At this level most graphs are simply

sketched.

For most cubics the three x-intercepts and the y-intercept provide enough points to sketch the graph.
