- Math: Need Answer to study for a quizz. Help ASAP -
**drwls**, Thursday, November 18, 2010 at 8:51pmThe actual area is the integral of the f(x) function with x going from 1 to 3.

That is the value of x^3/3 -2x^2 +5x at x=3 minus the value at x=1.

Area = [9 - 19 + 15]-[1/3 - 2 + 5]

= 5 - 3 1/3 = 1 2/3

You will have to do the graph-drawing and numerical approximations to the integral yourself. Break the interval into eight rectangles. The width of each rectangle will be 1/4, and the height will be f(x) at the leading value of x.
