Find the total area betwen the curve y=x^2-4 and the interval [0,3].

## Homework Equations

## The Attempt at a Solution

Okay, so I already know the answer, but I'm unsure about one thing.

It's ture that you have to break the equation such that it says [tex]\int_{2}^{3} x^2 dx[/tex] - [tex]\int_{0}^{2} 4 dx[/tex], but how would you go about finding which upper and lower limits to set for the two integration problems like that?

I know how to take care of the rest once I find those, but I'm not sure how to get the upper and lower limits once I break the equation into two.
