Best ResponseYou've already chosen the best response.0Use trapezoidal rule. If you look at a plot of your function, you'll see that it falls roughly linearly from 0 to 2.

Best ResponseYou've already chosen the best response.0You should know that the area of a trapezoid is \[\frac{1}{2}(a+b)h\]where a and b are the 'top' and 'bottom' and h is the altitude (or height). Here, a=f(0), b=f(2) and the height is (ba)=2
