Please help my solve this question: Two rockets are shot into the air from the same location. The paths of the rockets are given by

#1: y = -0.025x^2 + 3x - 52.5,

and #2: y = -0.04x^2 + 0.1x + 40.

Which rocket goes higher, and by how much?

I'm uncertain as to how I should solve this. Assistance would be much appreciated. Thank you.
