Question 1208234
what is the height of the coin when it is tossed?  -16x^2+96x+112 

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
