M – Functions, Lesson 2, Function Notation, Evaluating Functions (r. 2018)FUNCTIONSFunction Notation, Evaluating FunctionsCommon Core StandardF-IF.2Use function notation, evaluate functions forinputs in their domains, and interpret statements thatuse function notation in terms of a context.Next Generation StandardAI-F.IF.2Use function notation, evaluate functions forinputs in their domains, and interpret statements that usefunction notation in terms of a context.LEARNING OBJECTIVESStudents will be able to:1)use function notation,2)evaluate functions for specific input values, and3)use function notation in context.Overview of LessonTeacher Centered IntroductionOverview of Lesson- activate students’ prior knowledge- vocabulary- learning objective(s)- big ideas:direct instruction- modelingStudent Centered Activitiesguided practiceTeacher:anticipates, monitors, selects, sequences, andconnects student work- developing essential skills- Regents exam questions- formative assessment assignment (exit slip, explain the math, or journalentry)VOCABULARYfunction notationdependent variableindependent variablecomposition of functionsBIG IDEASFunction NotationIn function notation,f(x) is used instead of the letter y to denote the dependent variable.It is read as “f ofx” or “the value f(x) is a function of x,” which is the independent variable.Other letters may also beused.There are four primary advantages to using function notation:1)The use of function notation indicates that the relationship is a function.2)The use of function notation explicitly defines which variable is the dependent variable and whichvariable is the independent variable.3)The use of function notation simplifies evaluation of the dependent variable for specific values ofthe independent variable.
