Carefully graph the function             .

  1. Iveta wants to calculate the area under the curve for , so she decides to divide the region into ten trapezoids to approximate the area. Explain to Iveta why this is not the most efficient method.

    Can you find a way to calculate the area accurately with less than trapezoids?

    Because the function is composed of two linear pieces, the exact area can be computed using two trapezoids.

  2. Calculate the area under the curve for .
