You could make a table of 
values and then calculate the 
-values that correspond. But it would probably be helpful to compare this equation to the equation of a parabola with vertex at )
, namely
^2\ +\ k)
That gives you the vertex directly and allows you to plot two points for every one you calculate after that because of symmetry.
