Your nephew is standing on his deck, which is 4 feet off the ground. He tosses his toy up in the air at an initial velocity of 7 feet per second. The equation h=-2t^2+7t+4 models the toy’s height h in feet from the ground at t seconds after he threw it. A. How high is the toy after 1 second?
B. What is the toy’s maximum height?
C. How long is the toy in the air?
