The trajectory of an object moving through space is given by the quadratic equation:

d=-t squared + 6t

the value d represents the height off the ground of the projectile (in feet). The variable t represents the time ( in seconds)

How many seconds does it take the object to reach the highest point of its trajectory? What is the value of d at the highest point of trajectory?

How long does it take the object to reach the ground after it is launched.
