I. Estimating Area Under a Curve Suppose we want to estimate the area under the curve f (x) = x² + 1 between x = 0 and x = 4. TY 16 12 3. Suppose that the area under some curve is divided into n rectangles and we want the area under the curve between a and b.

We take the total width, 4 - 0 = 4, and divide it by the number of rectangles, 4, to get equal-width rectangles. Thus, each rectangle is width = 1.

Hi I really need help with how to answer question 3 in attached image, the one that asked the formula for the width, △x? 

thank you so much
