Use the data in your table above to create a graph on the grid below.

Draw acurve of best fit(do nottry to connect all the points. Draw a line that followsthe trendof themostpoints). Make sure to follow all the graphing rules from the checklist you received in class!

Give your graph a title.

Use your graph to answer the questions below:

4. a) [3A, 1C] Draw a secant line on your graph

and use it to determine your AROC for the whole

journey. Show any/all calculations below. Please

include the correct units of measure in your answer.

b) [1T] What does the AROC represent in this data? : _______________________________________

a) At which point on your graph did you experience your greatest IROC? ______________

b) Why did you choose this point?

6. [3A, 1C] Draw a tangent line on your graph at the point you chose in Q6. What is your IROC at this point? Show any/all calculations below. Please include correct units of measure in your answer.

7. [2T, 1C] At which point on your graph did you experience your lowest IROC? Why did you choose this point?

8. [3A, 1C] Draw a tangent line on your graph at the point you chose in Q8. What is your IROC at this point? Show any/all calculations below. Please include correct units of measure in your answer.

9. [2T, 1C]

a) If you were to create an equation to represent the data in your graph, what kind of equation would you choose (linear, quadratic, exponential, cubic, square root, etc.)? : ___________________________________

b) Why would this type of equation best represent your graph? Explain.
