Ethan and Claire 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 Ethan
.
The function f given by f(t) = -16t2 - 8t + 8 represents the height of a stone t seconds after it was thrown by Claire. In both functions, height is measured in feet.
-
Whose stone hit the water first? When did that happen?
-
Claire’s stone reached its maximum height second after it was tossed. Did Claire’s stone reach a higher maximum than Ethan’s stone?
-
What was the maximum height of Claire's stone?

Colby is standing on a bridge and using a catapult to throw
rocks of the bridge into a lake. Suppose the function rr models the
relationship between the height above the lake (in feet) of any
rock thrown by the catapult in terms of the number of seconds
elapsed since the rock was launched.
