1, Using rectangles whose height is given by the value of thefunction at the midpoint of the​ rectangle's base, estimate thearea under the graph using the first two and then fourrectangles.
f(x)= x3 between x=2 and x=4
A, using two rectangles to estimate, the area under f(x) isapproximately = ---------?
B) using four rectangles to estimate, the area under f(x) isapproximately= ----------?
2, Using rectangles whose height is given by the value of thefunction at the midpoint of the​ rectangle's base​ (the midpoint​rule), estimate the area under the graph of the following​function, using two and then four rectangles.
y= 100 - x2 between x=-10 and 10
A) For two​ rectangles, area =------?
B) For four rectangles, area= ------?
