Arocket is launched vertically from the ground with an initial velocity of 64 ft/sec. (a) write a quadratic function h(t) that shows the height, in feet, of the rocket t seconds after it was launched. (b)graph h(t) on the coordinate plane.

The equation would be: h(t) = -16t^2 + 64t.

This is a basic quadratic equation regarding objects being launched into the error. The -16 is the number that is derived from the value of the force of gravity. 

The 64 represents the initial velocity.

Since it is launched from the ground, there is no constant at the end.

For your graph, it will be an upside down parabola that starts at the origin.
