Use a graphing calculator to graph the function and visually determine the intervals on which the function is increasing, decreasing, or constant.

f(x)= 4x, x<2

f(x)= 8, 2<x<6

f(x)= -1/2x+11, x>6

I think my biggest problem with this question...is that I don't understand the question. I have never had a problem like this before and am not sure how to graph this with my calculator or what is meant by visually determining the intervals...Help, please?
