### Applications - Introduction to Functions

A bullet shot straight up is s feet above the ground after t seconds, where s = f(t) = -16t^2 + 256t. Find the height of the bullet 3 seconds after it is shot.

this 1 works just like UR other 1:
put 3 in for t & simplify to get s

So put it like this:

f(3) = -16(3)^2+256(3)
