Ahovercraft takes off from a platform. its height (in meters), xxx seconds after takeoff, is modeled by: h(x)=-2x^2+20x+48h(x)=−2x 2 +20x+48h, left parenthesis, x, right parenthesis, equals, minus, 2, x, start superscript, 2, end superscript, plus, 20, x, plus, 48 what is the maximum height that the hovercraft will reach?

the maximum height is the y-value of the vertex.

h(x) = -2x² + 20x + 48

       a=-2, b=20, c=48

h(5) = -2(5)² + 20(5) + 48

      =  -50   +  100   + 48

      =          50         + 48

      =                98

98 meters
