The graph shows the height (h), in feet, of a basketball t seconds after it is shot.
Projectile motion formula: h(t) = -16t^2 + vt + h0

v = initial vertical velocity of the ball in feet per second
h0 = initial height of the ball in feet

Complete the quadratic equation that models the situation.
h(t) = –16t^2 + _t + 6
