The (time, height) graph y = a(x h)2 + k of a small projectile contains the vertex (2
Chapter 9, Problem 12(choose chapter or problem)
The (time, height) graph y = a(x h)2 + k of a small projectile contains the vertex (2, 67) and the points (0, 3) and (4, 3). You can find the particular equation of this graph by substituting (2, 67) for (h, k) in the equation, then finding the value of a by substituting the coordinates of one of the other points for x and y. What is the particular equation?
