    Re: Quadratics

    In A1 type x; in B1 type y
    In A2 type -20, in A3 type -19
    Select A2:A3 and drag the fill handle (little box in lower right corner of
    cell) down to A36 (A6 will get value 14)
    In B2 type =A2^2+6*A2-72 (hope you see where I got this)
    Copy B2 down to B14
    Select A1:B14; click the chart Wizard and plot an XY chart
    best wishes
    Tell us what mark I get for YOUR homework!
