Joe drops an egg from the top of a building 300 feet tall. The vertical distance is represented by the function h(t) = -16t2 + 300 where h(t) is the height of the egg, in feet, and t is the time, in seconds.
The egg touches that ground after this many seconds.
What is approximately 4.33 seconds?

These points (3, -7), (2, 0), (1, 5), (0, 8), (-1, 9), (-2, 8), (-3, 5), (-4, 0) represent the table for a graph and can be used to classify the graph as this.
What is quadratic because the second common difference is +2?
300
This pattern is drawn on the board.
What is quadratic in nature?

If there is a common ratio the graph is classified as this.
What is exponential?

Joe drops an egg from the top of a building 300 feet tall. The vertical distance is represented by the function h(t) = -16t2 + 300 where h(t) is the height of the egg, in feet, and t is the time, in seconds.
The egg reaches this maximum height.
What is 300 feet?

From the top of a 3-foot podium a sea lion jumps into a large tank of water. The height of the sea lion at any time t is modeled by the function
h(t) = 0.5t2 – 4t + 3.
The seal lion reaches this minimum height.
What is -5 feet?

From the top of a 3-foot podium a sea lion jumps into a large tank of water. The height of the sea lion at any time t is modeled by the function
h(t) = 0.5t2 – 4t + 3.
The sea lion is at the surface of the water at these times.
