Jamal wrote the following Riemann sum to estimate the area under

  1. Draw a sketch of the region. How many rectangles did he use?

    General form of left-endpoint Riemann Sum:

    There are rectangles.

    The function is

    This is where the region starts.

    Each rectangle has a width of .

  2. For what domain of did Jamal estimate the area?

    Refer to the graph in part (a).

  3. Use the summation feature of your calculator to find the approximate area using Jamal's Riemann sum.
