Do your students ever wonder why they need to learn to graph a parabola? Talk about dropping an egg from a height of 500 ft, jumping off a diving board, throwing a football, and how long it takes to empty a water tank. This section includes in-depth teacher examples, in-class practice exercises, and a detailed assignment with answers. Help your students practice inputting functions, changing window size and understanding basic information provided by a graph. One of the funnest activities of the year!
