Introduction to Parabolas
Interpret parabolas in context
1. Biologists introduced a population of bacteria to a test environment. The function 
models the population size (in thousands) as a function of time (in days) after introduction.
Plot the point on the graph of that corresponds to when there are no more bacteria in the population.
2. A baby bird jumps from a tree branch and flutters to the ground. The function models the bird's height (in meters) above the ground as a function of time (in seconds) after jumping.
Plot the point on the graph of that corresponds to the bird's height above the ground when it jumped.
3.Cassie hit a golf ball. The function models the height of the ball above the ground (in meters) as a function of time (in seconds) after Cassie hit it.
Plot the point on the graph of that corresponds to the ball's maximum height.
4. Mia kicked a football. The function models the height of the ball above the ground (in meters) as a function of time (in seconds) after Mia kicked it.
Plot the point on the graph of that corresponds to when the ball hit the ground.
