it is C right? ive been trying to get this question answered for the passed 2 hours ahahah @SolomonZelman

@perl

OpenStudy (perl):

did you graph the region (thats what i would do first)

OpenStudy (perl):

the form of the integral is integral ( top curve - bottom curve) dx

OpenStudy (wade123):

yes! x^2 is a parabola,

OpenStudy (danjs):

It is the semi triangular looking region

OpenStudy (danjs):

You should divide that up into two regions and add it together x from 0 to 1, then from 1 to 2

OpenStudy (danjs):

The first is the area below x^2 from x = 0 to x = 1

OpenStudy (danjs):

The second is the area below y = 2 - x, from x = 1 to x = 2

OpenStudy (danjs):

THe integral of a SUm is the sum of the integrals,

OpenStudy (danjs):

can you see that on the graph clearly?

OpenStudy (wade123):

yes! im looking at it now(:

OpenStudy (danjs):

Wow i didnt look at the answer choices. that makes it pretty obvious.. haha sorry

OpenStudy (danjs):

Just remember, the integral over the two bounds is the area underneath the curve. You need one that will sum up to give the region you are looking for.

OpenStudy (danjs):

The first answer choice, gives the region above the line and below x^2 curve, that is not the region you want.
