Big Idea Problems that exist within the real-world, including seemingly random bivariate data, can be modeled by various algebraic functions. This lesson builds on students’ prior work with exponential modeling. This task focuses on the bivariate data from a study of a new bacteria to determine its growth model. This builds towards their understanding of how polynomials can be used in regression systems modeling, which comes up later in Algebra 2 and in Advanced Placement and college level courses. Vocabulary: Exponential, Regression, Model, Coefficient of Determination Special Materials: Graphing Calculator or spreadsheet software for regression modeling.
