This sketch allows students to experiment with the parameters in standard and vertex forms of quadratic functions. After gaining some experience with those forms, there is a game to play.[br][br]Clicking target practice makes the graphs go away. Set the parameters to try and match the purple parabola. With which form do you have the most confidence?[br][br]When you're ready, try the game! Here's that applet: [url=https://www.geogebra.org/m/VwAjXFNE]https://www.geogebra.org/m/VwAjXFNE[/url]
