(08.01 MC) A food packet is dropped from a helicopter and is modeled by the function f(x) = −12×2 + 19200. The graph below shows the height f(x), in feet, of the food packet at different times x, in seconds: Use the graph to determine the domain of f(x) for all viable x values based on the context.

(08.01 MC) Bret threw a baseball up in the air. The following table represents the height f(t), in meters, of the ball above the ground at time t seconds: Time (t)(in seconds) Height f(t)(in meters) 0 3 2 4 4 3 6 0 Which of the following is represented by the y-intercept of f(t)?

(06.05 MC) Iris is a botanist who works for a garden that many tourists visit. The function f(s) = 2s + 25 represents the number of flowers that bloomed, where s is the number of seeds she planted. The function s(w) = 25w represents the number of seeds she plants per week, where w represents the number of weeks. Part A: Write a composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks. (4 points) Part B: What are the units of measurement for the composite function in Part A? (2 points) Part C: Evaluate the composite function in Part A for 30 weeks. (4 points)
