Use a fiNite Approximation to Estimate the Area Under the Graph

Use a finite approximation to estimate the area under the graph of the given function on the stated interval as
instructed.
- $$f ( x ) = x ^ { 2 } \text { between } x = 4 \text { and } x = 8 \text { using the "midpoint rule" with four rectangles of equal width. }$$
