Inscribed rectangles are below a curve. Circumscribed rectangles are above a curve. 
For the function , complete the following problems.

  1. Calculate the area from using four inscribed rectangles

    Some of the rectangles will be left-endpoint and others will be right-endpoint.

    Inscribed means that only one point of the inscribed shape is touching the function. The rest of the points lie within the function.

  2. Calculate the area from using four circumscribed rectangles.

    Circumscribed means the shape you are drawing must entirely contain the function. The function is inside the shape.

  3. Estimate the actual area using your answers to parts (a) and (b).

    What shape is this? Use geometry.
