The problem has not been written correctly
h(x) = -16x^2+96x+112
h isheight and x is the time
find the maximum height (whic we need to find the vertex of this quadratic equation.
using the formula for the vertex of a parabola:
x= -b/2a
a=-16 , b=96
x= -96/-32= 3 seconds
maximum height occurs at x =3 seconds
plug x = 3 in the equation
h(3) = -16*3^2+96*3+112 =256

The maximum height of the coin is 256 units
