] Estimate the area under the graph of f(x) = 1/1 + 4x^2
from x = −2 to x = 0 using four
approximating rectangles and
(a) right endpoints (R4).
(b) left endpoints (L4).
(c) midpoints (M4).
Carry any intermediate calculations to four decimal places, and round your final results to two decimal
places.
