  e0.04x dx     is equal to 25(e - 1)

 
[2] (a)(part of #13 Pg 438)(3 pts) At the right are the graphs of
[ y = x3 - 3x2 ] and [ y = x2 + 5x ].
      Region A     Region B
Without using a graphing calculator, express the region B (to the right of the y-axis) between the two graphs at the right as a single definite integral by entering specific integers (such as 3, -2, or 0) in the 6 empty answer boxes below. Show some algebraic work, especially in finding the two limit numbers a and b immediately to the right of the integral sign.
