    google :) http://www.wolframalpha.com/input/?i=plot+Piecewise [{{x%2F25%2C0%3C%3Dx%3C5}%2C{2%2F5-x%2F25%2C5%3C%3Dx%3C%3D10}%2C{0%2Cx%3E10}%2C{0%2Cx%3C0}}]

    you have to erase some peaces of x2 for x>3 and draw x+2 instead of that .

    I guess you have to make your question is wolfram.

    Refer to the attached Mathematica plot. This is the first use of the Piecewise function for me.

    The above plot generated with the following Mathematica statement:\[\text{Plot}\left[\text{Piecewise}\left[\left\{\left\{x^2-5,x\leq 3\right\},\{x+2,x>3\}\right\}\right],\{x,-4,10\}\right] \]

    For your information, Mathematica can take the derivative of a piecewise function.
