Use the Midpoint Rule with n = 4 toapproximate the area of the region bounded by the graphof f and the x-axis over theinterval.
f(x) = x2 + 2x
Use the Midpoint Rule with
n = 5
to approximate the area of the region bounded by the graphof f and the x-axis over theinterval. (Round your answer to four decimal places.)
f(x) = (x2 + 7)2/3
