Solution 16EStep 1:Graphing parabolas Sketch the graph of the following parabolas. Specify the location of the focus and the equation of the directrix. Use a graphing utility to check your work.4Step 2:The standard form is of a parabola is , where the focus is (h, k + p) and the directrix is y = k - p. If the parabola is rotated so that its vertex is (h,k) and its axis of symmetry is parallel to the x-axis, it has an equation of , where the focus is (h + p, k) and the directrix is x = h - p.
