Question

A ball is thrown from the top of a wall onto horizontal ground.


The path of the ball is modelled by the function f(x) =6+8x-x^2 , where x represents the horizontal distance the ball is thrown and f(x) represents the height of the ball above the ground. All distances are measured in metres.


The wall lies along the y-axis. The curve intersects the y-axis at point A and has its vertex at point B.


From which height in metres was the ball thrown? Briefly explain your reasoning.
