find the extreme values of the function on the interval and where they occur.
f(x) = |x-1|-|x-5|, -2<=x<=7
How do I do this? Sorry for double post. I really need to do this,
I don't see an easy way. You can graph it, there is not anything here that would take long to graph. graph at -2, 0, 1, 5, 7
Don't I have to take derivative of f(x)?
I don't think you will get a maxima, what you will get will be extremes at some of the critical points on the graph. Taking the derivatives on a linear function with abs doesn't reveal much.
OK please tell me how to solve this.

f(x) = abs(x+2)-abs(x-3), -infinity<x<infinity
