y=   -20/9x^2 + 20/3x

x=   -(20/3) / 2(-20/9)
x=   -(20/3) / (-40/9)
x=   3/2

The axis of symmetry represents the distance from Diana in which the ball reaches it's maxium height.

Plug in the axis of symmetry for the 'x'  value in the quadratic equation.

y=   -20/9x^2 + 20/3x
y=   (-20/9)(3/2)^2 + (20/3)(3/2)
y=   (-20/9)(9/4) + (20/3)(3/2)
y=   -5 + 10
y=   5

Vertex: (3/2 , 5)
The vertex represents the maximum height the tennis ball reaches while bouncing.]]> 2016-12-08 03:44:44 UTC https://padlet.com/garciad1269/zzssj7p0i2vr/wish/142461549 garciad1269 https://padlet.com/garciad1269/zzssj7p0i2vr/wish/142464021 Our roots are {0,3}, which represent where the ball hits the ground on the initial bounce and where it hits again.]]> 2016-12-08 04:32:36 UTC https://padlet.com/garciad1269/zzssj7p0i2vr/wish/142464021 garciad1269 https://padlet.com/garciad1269/zzssj7p0i2vr/wish/142465195 2016-12-08 05:00:58 UTC https://padlet.com/garciad1269/zzssj7p0i2vr/wish/142465195
