The path of a projectile, projected from the point AAA, can be modelled by the equation
y=−0.25x2+2.125x−4.125 y = -0.25x^2 + 2.125x - 4.125 y=−0.25x2+2.125x−4.125Find the coordinates of the point AAA
Find the distance from A A\,A that the projectile hits the ground.
Calculate the maximum vertical height of the projectile
