Question

Let f(x) = 4 - . Calculate the lower and upper sum estimates of the area under the curve over the interval [2,5] using subintervals of width ½. I understand the general concept, but am having trouble finding the f(M1) and f(m1).

Answer 1

\[f(x)= 4- \frac{ 12 }{ x^2 }\]

Answer 2

Corrected Function Above! Thank you in advance!
