1. A softball is hit by a batter when it is 3 feet off the ground. Its height off the ground is given by h(t) = -16t2 + 80t + 3, where h is in feet and t is in seconds. Use Desmos to graph h(t) on a domain so that the h – and t -intercepts are visible on the graph. Write down those points. а. b. Use the graph to find the maximum height of the ball. How long after the ball is hit does it reach it's maximum height? i. Describe how you read that off the graph ii. Describe how you can find it algebraically based on the function.
