Answer:
The platform was 277 feet high at the time of the launch
Explanation:
Given that the height is modeled by:
[tex]h\mleft(x\mright)=-4\mleft(x-2\mright)^2+293[/tex]To find how high the platform was at the time of the launch, we find h(0) by replacing x by 0 in the given equation.
[tex]\begin{gathered} h(0)=-4(0-2)^2+293 \\ =-4(-2)^2+293 \\ =-4(4)+293 \\ =-16+293 \\ =277 \end{gathered}[/tex]The platform was 277 feet high at the time of the launch
