The paths of two dolphins playing in the ocean were recorded by some biologists. The first dolphin’s path could be modelled by the equation h( ) = 2^4 − 17t^3, + 27^2 −
252 + 232 and the second dolphin’s path could be modelled by the equation h() = 20^3, − 200^2 + 300 − 200.When was the first dolphin higher than the second dolphin?
