a) Estimate the area under the graph of f(x)=7+4x^2 from x=-1 to x=2 using three rectangles and right endpoints.
R3= ???
Then improve your estimate by using six rectangles.
R6= ???
Sketch the curve and the approximating rectangles for R3 and R6?
b) Repeat part (a) using left endpoints.
L3= ???
L6= ???
Sketch the curve and the approximating rectangles for L3 and L6?
c) Repeat part (a) using midpoints.
M3=????
M6=???
Sketch the curve and approximating rectangles for M3 and M6?
d) from your sketched in parts (a)-(c) which appears to be the best estimate??
R6 or M6 or L6 ????
Please help me with this I only have one try left on WebAssign.

I can't sketch it. The instructions are really clear. Sketch the curve, and limits, draw the rectangles. Put the endpoints on the curve, add the areas.
