The equation h=-16t^2 + 32t +9 gives the height of a ball, h, in feet above the ground, at t seconds after the ball is thrown upward. How many seconds after the ball is thrown will it reach maximum height? What is its maximum height?
the vertex of any parabola is given by (-b/(2a)) the value of this is how many seconds plug this value into the equation to get the max height
I figured out i wanted to check cause it is important thank you very much
