Algebra 2 | Linear Functions and Applications

Unit Summary

In Unit 1, students review and extend the Algebra 1 skills of graphing, manipulating, and describing solutions to linear functions to deepen their understanding of modeling situations using linear functions. In this unit, students review concepts, such as using multiple representations, inverse, constraints, and systems, that are essential for studying polynomial, rational, exponential, and logarithmic functions, and trigonometric functions in later units through linear functions, a familiar and basic parent function.

Unit 1 begins with students translating between representations of linear functions to identify the strengths of each representation and to highlight features of linear functions. The inverse of a linear function is studied through contextual situations, to ensure that students grasp the symmetry between a function and its inverse, as well as connect the meaning of each variable and its role (dependent or independent) in the concept of inverse. Topics in this unit continue through systems—a concept that is very familiar to students. The focus in this section of the unit is again contextual as well as procedural to allow students to be fully fluent in solving systems algebraically, graphically, with three variables, and with absolute value functions, an application of a linear function. Students review piecewise functions through a linear lens to bolster their facility with constraints and analysis of functions in preparation for nonlinear piecewise functions. Students who are taking the pre-calculus portion of this course will continue on to compose functions within and outside of context to model and identify solutions to real-life scenarios.

As Algebra 2 progresses, students will draw on the concepts from this unit to find the inverse of functions, restrict domains to allow a function to be invertible, operate with various functions, model with functions, identify solutions to systems of functions graphically and algebraically, and analyze functions for their value and behavior. Mastering the skills in this unit will allow for students to have a solid framework to build upon when studying other functions.

Essential Understandings

The central mathematical concepts that students will come to understand in this unit

A linear relationship can be represented contextually, graphically, in a table of values, and algebraically. By manipulating a linear function algebraically, including finding the inverse of a linear function, relationships of the linear function are highlighted.
Contextual situations often have limitations that need to be represented by constraints on the domain or the range of the equation to accurately represent the situation.
Systems of functions are used to show when two or more functions have the same value in contextual and non-contextual situations.
Piecewise functions model situations where more than one function is required, but those functions happen in sequence rather than simultaneously as in systems. Piecewise functions will, by definition, require constraints to describe when one function starts and another begins.
Functions can be composed where an output from one function is used as the input of another function to describe situations where operations are nested to describe relationships.
