(No. of marks)
A description of the environmental or community issue that needs to be addressed. 2/2
A description of the product or change in behaviour that could reduce the damage caused by the issue, with justification. 5/5
A set of secondary data from a reliable source, in table form, pertaining to the environmental issue. It must be appropriate for modeling with one of the types of functions studied in this course: polynomial of degree 3 or higher; exponential; logarithmic or trigonometric. A spreadsheet (Excel, Google Sheets etc.) could be used to create the table and would facilitate graphing the data. 8/8
: The APA reference for the data set. 2/2
A scatter plot of the data including appropriate titles, scales and units, created with the graphing technology of your choice. 5/5
An algebraic model that fits the data. The model can feature one of the functions mentioned above or could be a combination or composite of two of those functions. The choice of model should be based on visual inspection of data trends observed and does not need to be supported by statistical analysis, which is beyond the scope of this course. 4/4
An explanation of how the algebraic model was determined, including justification for the choice of parent function (or combined or composite function) and any transformations used to model the data. 5/5
Restrictions on the domain of your function and a description, including justification, of potential limitations of the algebraic model as it applies to correlation with the data and the real world context. 5/5
A graph of the algebraic model, including appropriate titles, scales, units, and restrictions on the domain, created with graphing technology, and superimposed on the scatter plot.
5/5
At least one calculation using the algebraic model to make a prediction, or for emphasis. 4/4
A brief sales pitch, using the graph as evidence, and calculations involving the algebraic model to make predictions to convince the reality TV show panel that your proposal deserves support. 10/10
Correct use of mathematical terminology and conventions throughout. 5/5

Expectations
You will need to have chosen a relevant topic plastic waste, air pollution, global warming, disappearance of species are very concerning in our society
You will need to have found some compelling HISTORIC information and provided a data table.
NOTE: Providing a data table based on future projections is not adequate as that will be based on assumptions.
There MUST be a complete reference for the data table. It MUST be stated in such a way that I can simply perform a COPY/PASTE into a web browser and be immediately taken to the data table.
Then there are a few things that you will need to do:
1st: create scatter plots to illustrate the HISTORIC data table make sure that the graphs have reasonable scales, including calendar years along the horizontal axis (the years listed in your data table, rather than using 1,2,3).
2nd: look at your graph and determine which type of function that seems to best fit your graph. Note: The function you use must be of the type studied. Polynomials must be of degree 3 or higher.
(Linear Functions and Quadratics and not allowed)
3rd: Develop an equation that best fits the data The equation you develop should use the calendar years as the variable. You should also justify the values you are using:
4th: provide a graph that superimposes the equation you developed onto the previous scatter plot
5th: use you equation to make predictions for future results if nothing is done
6th: develop a presentation that will inform the panel of investors of the possible solutions, consequences of inaction as well as your plans to use their invstments
I look forward to what you do with the topic
I have included the rubric I will be using to grade your final submission. That way you know exactly what to expect
