APPLICATION The graph at right shows the graph of h(t) = 4.9t2 + 50t 97.5. The variable t represents time in seconds, and h(t) represents the height in meters of a projectile. a. What is a real-world meaning for the x-intercepts in the graph? b. Find the x-intercepts to the nearest 0.01 second. c. How can you use 9b to find the vertex of this parabola? d. What is a real-world meaning for the vertex in the graph? e. What does h(3.2) tell you? f. When is the projectile 12.5 m high? Explain how to find these solutions on a graph.
