H(x) = - (x-11)(x+3)
what is the height of the hovercraft at the time of takeoff?

33 feet

Step-by-step explanation:

height of hovercraft  x  seconds after takeoff  =  h(x)  =  -(x - 11)(x + 3)

We want to know the height of the hovercraft  0  seconds after takeoff.

height of hovercraft  0  seconds after takeoff  =  h(0)  =  -(0 - 11)(0 + 3)  =  -(-11)(3)  =  33

So...

The height of the hovercraft at the time of takeoff is  33  meters.
