You can put this solution on YOUR website!
the coefficient of the t^2 term should be negative

the calculator should display a parabola opening downward

the height is on the y (vertical) axis and the time is on the x (horizontal) axis

the vertex is (15/16,289/16)



BIG HINT: the vertex is the solution
