******PLEASE NO PLAGIARISMThe purpose of the Signature Assignment is to have you work with real-life data to answer a real-life question using the tools, technology, and skills of MTH/219. In Week 4, you will analyze your graphs.Graph the rational equation y = 1/x either in Microsoft® Excel® or using Desmos (see tutorial on how to use Desmos).Create a scatterplot of your data in Microsoft® Excel® (just a scatterplot without regression). You will use these graphs in a comparison.Answer the following questions in a Microsoft® Word document. Each question should be 260 to 350 words.What happens to the values of the rational function over time? This is a characteristic of inverse variation. Does your data also seem to follow this trend?What happens to the values of the rational function as you approach 0 from the right? Does your data also seem to follow this trend?Do you think this model is a good fit for your data? Why or why not?Save your Microsoft® Word document, graphed equation, and scatterplot. A good way to do this is to screenshot both graphs and put them in your Microsoft® Word document.Your assignment will be graded with the Week 4 Signature Assignment Grading Guide.Click the Assignment Files tab to submit your assignment.
