Question

The height above the surface of the Earth​ (in meters) of a rock thrown into the air at 10​ m/s after x seconds is given by f(x)=-9.8x^2+10x+1.5. On the surface of the​ moon, the height is given by g(x)=-1.6x+10x+1.5. How much higher does the rock travel on the moon than on​ Earth?
How much higher does the rock travel on the moon than on Earth? (Round to the nearest tenth if needed)
