Suppose I am on top of a UAB parking deck 144 feet above ground. While taking pictures of campus, I accidentally drop my phone over the side of the parking deck. The height of the phone, h, t seconds after dropping it may be represented by this quadratic equation: h = 16t² + 144 Use this equation to discuss these questions: a) What are your initial observations about this equation? There are no "right" or "wrong" answers here. I am asking you to look at this equation and share what you see or are thinking. In problem solving, it is good practice to do this first. b) After 1 second, how high above the ground is your phone? After 2 seconds, how high above ground is your phone? After 3 seconds? c) When will your phone hit the ground? Does your answer make sense to you? Why or why not?

Suppose I am on top of a UAB parking deck 144 feet above ground. While taking pictures of
campus, I accidentally drop my phone over the side of the parking deck. The height of the
phone, h, t seconds after dropping it may be represented by this quadratic equation:
h = 16t² + 144
Use this equation to discuss these questions:
a) What are your initial observations about this equation? There are no "right" or "wrong"
answers here. I am asking you to look at this equation and share what you see or are
thinking. In problem solving, it is good practice to do this first.
b) After 1 second, how high above the ground is your phone?
After 2 seconds, how high above ground is your phone?
After 3 seconds?
c) When will your phone hit the ground? Does your answer make sense to you? Why or why
not?
d) Use https://www.desmos.com/calculator to graph −16t² + 144 . What connections can you
