Precalculus Unit 2 Overview F2020 page 1Precalculus Unit 2: Function Algebra(Onlevel: Tuesday 9/15 to Thursday 10/1) / (PreAP: Thursday 9/17 to Thursday 10/1)This unit is all about becoming pros at functions!You will be experts at domain and range of all different function types, including composite and inverse functions and be able to determine and evaluate composite and inverse functions whether given a graph, a table of data, or an algebraic representation (f(x)). Although this is partially a review of Algebra I, the problems and applications are more complex, so don’t underestimate this unit! If you struggle with fractions make sure you come to drop in help! Objectives:Determine the domain and range of a function given its algebraic representation or its graphCompute, graph, and interpret the sum, difference, product, quotient, and composition of two functionsDetermine if a function has an inverse that is also a function and, if so, find the inverse algebraically or by graphingUse the composition of functions to verify the inverse of a functionRestrict a function’s domain to find its inverse functionImportant Resources and InformationKey Concepts and Key Words: Function Algebra Key Conceptsand Function Algebra Key Words. These are from your review lesson and are also located on the message board.Extra Credit Quiz and Test Review Recordings –Use these to review for the quiz and test and earn extra credit. There are two opportunities to not only earn extra credit but to also better prepare for the quiz and test! What a deal! Complete these review guides for the quiz and/or test.
