3. The graph of f() =-r is shown below on the interval (0, 1.5). Approximate the area "under" this curve using n =5 rectangles. Instead of using the typical right-hand, left-hand, or midpoint rules, use the following sample points inside each interval to construct the height of the rectangles: = 0.2, =0.5, 3=0.7, =1, =14 Be sure to calculate Ar first and sketch your rectangles on the graph provided. If necesary. round your answers to 3 decimal places.
