Homework Help: Graph each function on (-4,4)

  1. Sep 15, 2008 #1
    1. The problem statement, all variables and given/known data
    Grapher: Graph each function on (-4,4), and identify the point(s) at which the function is not differentiable.

    2. Relevant equations
    Graph F(X) = (X^2-2x+1)^1/3 on [4,-4] and Identify any points of discontinuity.

    3. The attempt at a solution
    I plugged in the F(x) equation on my calculator and I don't how to graph it on [-4,4]? I tried tracing the F(X) graph but I don't see the graph hitting the pt [-4.4] anywhere, am I doing this wrong?

    Re: Differentiability

    Another thing after thinking about it a bit more, when it says Graph it on [-4,4] does it mean that the F(x) equation has to to touch that point? If it does its continous? If it doesn't it does not exist?
