1. Given the graph of a ball being thrown from a catapult, answer the following questions. The vertical axis represents the height of the ball, the horizontal axis represents the distance from the catapult.
2. You throw a basketball whose path can be modeled by the graph of 𝑦 = −16𝑥2 + 19𝑥 + 6 where x is the time (in seconds) and y is the height (in feet) of the basketball.
3.
a. How far away from the catapult does the ball land? What part of the graph tells you this?
b. What is the maximum height the ball goes? What part of the graph tells you this?
c. Is the value of “a” positive or negative? How do you know?
