How can you find the vertex of a parabola?
If Paul throws a ball upward with an initial speed of 48 feet per second, and its height h in feet after t seconds is given by the function h(t) = -16t^2 + 48t, what is the maximum height of the ball?
How do you find the vertex of the equation h(t) = -16t^2 + 48t?
What is the formula for finding the x-value of the vertex of a parabola?
How can you figure out when a ball hits the ground if it is thrown into the air?
How can you figure out when h(t) = -16t^2 + 48t equals 0?
How do you solve -16t^2 + 48t = 0?
