All right. Here's the problem.
Use this principle:
If m ≤ f(x) ≤ M for a ≤ x ≤ b, then m(b-a) ≤ the integral ≤ M(b-a)
And here's my specific problem:
Use that property along with what you know about the function to estimate the value of

the answer should be in the form of "something" ≤ the integral ≤ "something"
Does that make sense? Help?
