Transformation of Quadratic Functions
Before using this applet you should know about the "completed square" or "vertex" form of a quadratic equation.
Use the sliders to change the values of the parameters in the completed squrae form of the equation. See how the shape of the graph varies. Fit a quadratic graph to the points (1, 5) (the vertex), (2, 6) and (3, 9) Fit a quadratic graph to the points (-3, -2) (the vertex), (-2, 0) and (-1, 6) Try to work out what the equation will be first, and then use the applet to check your solution.
