Name /50 . Understand the Problem Chapter 4 Project . Develop a Plan . Carry Out the Plan Population . Look Back There are many situations where we use linear functions to model growth/decay. One of those is populations of cities. Though not every city grows at a linear rate, linear models are still often used as an initial estimation. This is because they are very available and understandable. In this project you will be building two linear models simultaneously to compare two cities of your choice. As you begin this project note the two columns each identified for different cities. Though you may use your own research the website https://population.us/settlement/ may be helpful. 1 . City one : Rock Springs , wy 1 . City Two : Cheyenne , Wy 2. The city you chose above will be 2. The city you chose above will be your city of interest now. your city of interest now.
