the graph of the function tell me? How do they derive the function

for the speed of a bullet?

This is a good example of an applcation of a quadratic equation. I like how Mrs. Donley made the problem entirely in the storyline of finding the shooter--very creative. I would have liked to see Mrs. Donley go through and solve the problem according to the steps she suggested. Also, her question about the graph went off screen, so it was hard to tell what she was asking.

Mrs. Donley presents a fun example that entertains and engages viewers. I like how she explains the equation (height at time t) to be used when solving this problem. I like that she incorporated a graph and did not just plug in numbers. It would have been nice to have a description of the graph at the end explaining that since the maximum height of the bullet exceeds 7000 feet, that gun was used. Overall, this is a really nice video.
