Can y’all help please

 0 ft, maximum, 11.6 ft, 6.8 ft, 13.6 ft

Step-by-step explanation:

y = -0.25x² + 3.4x

   a= -0.25    b = 3.4    c = 0

"c" is the initial height = 0

"a" is negative ⇒ ∩-shaped parabola ⇒ vertex is a maximum

Axis of Symmetry (horizontal distance at maximum):

Maximum: (heighth at maximum)

y = -0.25(6.8)² + 3.4(6.8)

   =    -11.56      +    23.12

   =  11.56

Zeros (when the ball is on the ground):

0 = -0.25x² + 3.4x

0 = x(-0.25x + 3.4)

0 = x                      0 = -0.25x + 3.4

                          -3.4 = -0.25x

                          13.6 = x

x = 0 is where the ball started

x = 13.6 is where the ball landed
