7-78.

Write several sentences explaining to someone, who just transferred into the class, how to approximate the area under the curve $y=x^3+2x+6$ for $−1\le x\le3$. Do not actually approximate the area, just explain how to calculate it.

Think about the steps and order you take to find the area under the curve.
It may be easier to make a list first of ideas, then write in complete sentences.
