How to Graph a parabola properly in vertex form
This video shows viewers who are interested in mathematics how to graph a parabola whose formula is displayed in vertex form, or the form y=a(x-h)^2+k, where the vertex is (h, k). After determining the vertex, plot it on your graph. After graphing your vertex, your axis of symmetry would be x= h, or the x-coordinate of your vertex. The a value in your equation will act as your slope in this case, and your should graph the two points which correspond to this slope on your plot 1 unit away on either side of your vertex. Continue by choosing an x value and plugging it into the equation to determine the needed y value of each point and then finish your parabola by connecting all the points.
