FR 0568 #10

Post by rhnsrbh » Sat Mar 27, 2010 5:09 am

Hey is there anyone who can solve this?

In the booklet, there is a graph given, it is highly unlikely that i can put it up here.

Here s the question...

Let g be a function whose derivative is continuous and has the graph shown above. Which of the following values of g is the largest?

is it A g(1)?, B g(2) ?, C g(3)?, D g(4)? or E g(5)???

Estimate the integral at each of those points. Assume g(0) = 0, and then g(1) is the area of that little trapezoid bounded by the graph, x-axis, x=0, and x=1. g(2) is the whole triangle above the x-axis. g(3) is the triangle minus the smaller triangle, etc.
