Arocket was launched into the air from a platform above the ground. the height, in feet ,of the rocket above the ground t seconds after being thrown can be determined by -16t^2 64t 80 .what does the 80in this expression represent

The rocket was launched from the platform which is 80 feet above the ground.

Step-by-step explanation:

We are given,

The function representing the height of the rocket launched from the platform after t seconds by,

Now, when t = 0, we get,

i.e. f(0)= 80

That is, the height of the rocket at t = 0 seconds is 80 feet.

Thus, 80 represents the height of the rocket above the ground.

Hence, the rocket was launched from the platform which is 80 feet above the ground.
