If the area under the curve of f(x) = x2 + 2 from x = 1 to x = 6 is estimated using five approximating rectangles and right endpoints, will the estimate be an underestimate or overestimate?

Question

Underestimate

Overestimate

The area will be exact

The area cannot be estimated with just five rectangles <-MY ANSWERR

Answer 1
