Examine trends in student-to-teacher ratios over time. Building from the first task in the two-part series, classes now explore the pattern of student-to-teacher ratios using a non-linear function. After trying to connect the pattern to a polynomial function, learners realize the ratio does not fit these models. They then use a ratio to establish a rational function to achieve the asymptotic behavior of the graph. As a project-based learning task, they present their findings in an official report.
