rectangles. (Assume the graph goes through the midpoint of each rectangle.)

- math question 2- very urgent ! -
**TutorCat**, Monday, December 20, 2010 at 3:14am(sigma)M = (b-a) f((a+b)/2)

width:

(b-a)=2-0

(b-a)=4-2

(b-a)=6-4

(b-a)=8-6 =2

find the height:

f((a+b)/2)

(e.g. ([√(7 + a) + 4] + [√(7 + b) + 4])/2)

take the sum of "rectangles" (i.e. product of width and height)

rectangle method:
