A rock is launched from a connon. Its height, h(x) can be repersented by a quadratic function in terms of time, x, in seconds.

After 1 second, the rock is 94 feet in the air, after 2 seconds, it is 176 feet in the air.

complete the height function, h(x) for this situation

@DanJS 
Could you help?

$$y=y _{0}+v _{0}*t+\frac{ 1 }{ 2 }g*t^2$$

Initial height is zero
Given 2 points, (t,y)
g is the acceleration of gravity -32 ft/s^2
find initial velocity
