Chapter 9, Problem 6(choose chapter or problem)
APPLICATION A flare is fired into the air from the ground. It reaches its highest point, 108 m, at 4.70 s. It falls back to the ground at 9.40 s. a. Name three points that the graph goes through. b. Name a graphing window that lets you see those three points. c. What are the coordinates of the vertex of this parabola? d. Find an equation in the form y = a(x h)2 + k that fits the three known points. You may need to guess and check to find the value of a. e. Find h(3) and give a real-world meaning for this value. f. Find the t-values for h(t) = 47, and describe the real-world meaning for these values.
