since f'(x) = -1 which is never zero, there are no relative min or max points.

So, the extrema will just be the values at the endpoints of the interval. So, just find f(-1) and f(2).

I mean, don't forget your Algebra I just 'cause you're in calculus now. f(x) is just a straight line, doncha know...
