Unit 5, Activity 6, The Family of Functions - Sine and Cosine Part I Blackline Masters, Advanced Math-Pre-Calculus Page Comprehensive Curriculum, Revised 2008 167 Part I: Below are the graphs of the parent functions f( x ) = sin x f( x ) = cos x Today we are going to study the families of each of these two functions: f( x ) = A sin (Bx + C) + D and f( x ) = A cos (Bx + C) + D . Begin by answering the questions below: 1. What will the value “ A ” in f ( x ) = A sin x do to change the graph of the sine function? the cosine function? What do you know mathematically that will give credence to your answer? ______________________________________________________________________
