IA1.AT.D.14: Represent functions using tables and graphs, and interpret key features in context. Key features include: domain, intercepts, intervals of increase and decrease, positive and negative values, end behavior, asymptote, and points of transition between pieces. a. Analyze linear and exponential functions by identifying patterns in tables and graphs. Distinguish between constant and proportional growth. b. Extend the understanding of functions to include piecewise-defined and absolute value functions. Represent them in tables and graphs and explain how absolute value functions can be represented as a specific case of piecewise functions. c. Relate key features of a function’s graph and table to the characteristics of a context, and justify the appropriateness of a function model based on that context.
