Drawing Quadratic Graphs

Learn how to plot quadratic curves, using a table of values. Quadratic curves are either a U shape, if they are positive quadratics, or upside down U if they are a negative quadratic. To plot them onto a graph, substitute in x-values into the equation to generate the corresponding y-coordinate. These can then be plotted onto the graph. To plot a quadratic, there needs to be at least 5 coordinates to get the full curve shape, but probably more.
