Precalc question involving graphs?
I have to use my graphing calculator to "approximate the local maximum and minimum value of the function f(x) = -0.4x^3-0.5x^2+4x-6 for -6<x<4
I know how to find max and min and how to put the function into my calculator, but how do I solve it for -6<x<4?
Thanks in advance.

I just copied and pasted "f(x) = -0.4x^3-0.5x^2+4x-6 for -6<x<4"(without " ") into Wolfram and got a graph no problem.
