Lin and Clare were standing in the woods near a stream, and each threw a stone up in the air at the same time so that it would land in the water. The graph represents the height of a stone t seconds after it was tossed up by Lin. The function f given by f(t)=−16(t+12)(t−1) represents the height of a stone t seconds after it was thrown by Clare. In both functions, height is measured in feet.

a. Whose stone hit the water first?
When did that happened?
second after the stone was tossed

b. Clare’s stone reached its maximum height 14 second after it was tossed. Did Clare’s stone reach a higher maximum than Lin’s stone?

c. What was the maximum height of Clare's stone?
meters
