Homework Help: Algebra (Graphing Functions)

Posted by John on Wednesday, October 24, 2012 at 2:35pm.

Consider the following function.

f(x) =
−3x if x < −2
x2 if −2 ≤ x < 2
−3 if x ≥ 2

Please help me find the intervals on which f is increasing, is decreasing, or is constant(in interval notation). As well as the x and y intercepts for the graph.

Please help me out as I have been stuck on this for almost 20 min now and I keep getting it wrong. Any help is greatly appreciated!
