1. Find lower and upper sum lying between the graph f(x)= between x=1 and x=2 using 5 sub intervals.

A: Lower sum = 0.708353 | Upper sum = 0.645635

B: Lower sum = 0.645635 | Upper sum = 0.745635

C: Lower sum = 0.456667 | Upper sum = 0.645635

D: Lower sum = 0.456667 | Upper sum = 0.479500

2. Evaluate the integral

Given

(I believe the answer is -93 for the #2)

3. Use limits to find the area of the region bounded by the graph f(x)=4-2x^3, the x-axis, and the vertical lines x=0 and x=1
