A hovercraft takes off from a platform. Its height (in meters), x seconds after takeoff, is modeled by
\(h(x)=-(x-11)(x+3)\)
What is the height of the hovercraft at the time of takeoff?
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.
height of hovercraft x seconds after takeoff = h(x) = -(x - 11)(x + 3)
