Question

Kim is studying the sale of a particular brand of cereals from the year 2000 to 2010. She writes the following function to model the sale of the cereal S(t), in million dollars, after t years:

S(t) = t2 + 7t + 69

Part A: What does the y-intercept of the graph of the function represent? (4 points)

Part B: What is the reasonable domain of the graph of the function? (3 points)

Part C: What is the average rate of change of the sale of the cereal from the first year to the fourth year? Show your work. (3 points)

Answer 1

Part a. what does the y-intercept of the graph of the function represent?
the sale of the cereal at the start

Part B: What is the reasonable domain of the graph of the function?
The domain is the time from 2000 to 2010
Part C: What is the average rate of change of the sale of the cereal from the first year to the fourth year? Show your work
t^2 + 7t + 69
4^2 + 7(4) + 69
16 + 28 + 69
there answer

Answer 2

THAT IS YOUR ANSWER

Answer 3

Part a. the sale of the cereal at the start

Part B: The domain is the time from 2000 to 2010

Part C: What is the average rate of change of the sale of the cereal from the first year to the fourth year? Show your work
t^2 + 7t + 69
4^2 + 7(4) + 69
16 + 28 + 69
