(-1,1), (-1,-2) and (3,-2)
Homework Equations
The Attempt at a Solution
I'm having problems finding the boundaries for the integral. I know that we have:
-1<=x<=3 and -2<=y<=1.
I can also find the slope that it has and I found: y=-3/4x + 1/4.
From there, I don't know what to do. I know I'm supposed to choose if I want to integrate first, does it matter? or how can I know which one is easier?
I thought I could have something like: int(-1,3) int(1, -3/4x + 1/4) f(x) dA.
Hope someone can help me with this!
