I think the area of the curve is 23, but still need assistance/know if it's right and can you also help me with finding the exact area beneath the curve given in this problem by setting up an appropriate limit of a Riemann sum and evaluating that limit. We can't use an integral.

1. Give an approximation for the area beneath the curve y = = x2 + 2 from x = 0 to x = 4 using 4 rectangles with right endpoints. Draw a picture
