1. Press the ‘Get Form’ button to access the form and open it in the editor.
2. Begin with Task 1: Choose a U.S. city and find the rates of two different cab companies. If you have difficulty finding the rates, you may create reasonable estimates for the flat fees and per mile charges. Provide a written expression for the first company’s charges and write an equation in the selected form. Explain your choice.
3. For the first company, describe what the slope and y-intercept represent within this context. Consider what you pay when you enter the cab.
4. Move on to Task 2: For the second cab company, express the cost of a cab ride as a table based on the number of miles. Complete the table with values for 0 to 5 miles.
5. Write an equation in a slope-intercept, point-slope, or standard form. Provide justification for your choice and explain the meaning of the slope in this scenario.
6. Proceed to Task 3: Conduct research on average gas prices from 2005 to 2015 for the selected city. If this is not feasible, use national averages.
7. Create a table reflecting the average gas prices for each year and then generate a scatter plot based on this data.
8. Determine an equation that models the gas price data. Identify the domain and range of this equation and discuss the fit of the model to the data.
9. Analyze trends in the gas price data. Discuss whether there is a positive, negative, or nonexistent correlation and predict the gas price for 2020, providing reasoning for your prediction.
10. Once all tasks are completed, review your entries, save any changes made, and then download, print, or share your portfolio as necessary.
