    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.
