Find the height, in feet, of the missile after 5
seconds in the air.
A missile is launched from the ground. Its
height, h(x), can be represented by a
quadratic function in terms of time, x, in
seconds.
After 1 second, the missile is 243 feet in
the air; after 2 seconds, it is 452 feet in
the air.
The height of the can be represented by
this function:
h(x) = - 17x2 + 260x
