Put together everything that we have studied this fall, all the different types of functions: linear, quadratic, polynomials, rational, radical, exponential, and
logarithmic functions.
To complete this last assignment, go to the worldometers.info website, which has been reporting daily COVID-19 cases around the world since the beginning
of the pandemic. If you would like to look at the United States data, (https://www.worldometers.info/coronavirus/country/us/) just click the highlighted link.
For this assignment, you can pick any country or US state and look at any time period since the start of the pandemic.
Take your time looking around the website, carefully check out the different graphs, and try to understand any patterns or special features that you notice. As
you look through the data and use your mathematical knowledge to reason about it, try to articulate your thinking using the language of algebra. Do you see
any lines? Polynomials? Exponential growth? Logarithmic curves? Any maximum points or minimum points? Increasing or decreasing intervals? Domain and
range? etc.
For example: In the state of NJ, we have seen five maximum points since March 2020. I marked them with a highlighter. Last winter, we saw two maximums,
followed by one more in April, so I wonder what this winter/spring will look like. (graph on file)
Once you have a chance to look around and check out the information that interests you on the website, answer the following questions using vocabulary
and content from our course:
What did you notice or learn from the data provided on this website? Tell us a little bit about the country you studied and what you noticed. Use algebra
language and identify specific function types (polynomial, radical, exponential, etc) and their features (increasing/decreasing, max/min, domain/range, etc).
Make sure to justify your thinking. As much as possible, include examples of visual images like the one shown above to support your findings.
What are you still wondering about? What predictions can you make, if any, about the future COVID-19 situation for the country or state that you studied? If a
prediction is not possible, explain why not.
