The document appears to be a student's final project for an algebra 2 class. It includes sections on linear, quadratic, and exponential prediction models. For the linear model, the student predicts the population in 2061 using data from 1860. For the quadratic model, the student predicts a value using a 3-point quadratic equation. And for the exponential model, the student predicts the population in 2016 using 2 data points to define the exponential function.
