KEY QUESTIONS Lesson 12 1. Application [28, 12 marks] a) Complete the following table. [28 marks] Function Amplitude Phase Vertical Period shift Translation y = 2sin x+1 2 y =-3cos 2x 3 f(x) = sin x 4 +3 4 f(x) = 2cos~ x+ 5 y =-3sin(x -7)+1 6 f(x) =2cos x- 7 y= -2cos3| x+ -1 b) From the above table choose first function from numbers 1, 2, and 3; choose second function from numbers 4, 5, 6 and the third function will be number 7. For each of these three functions, list the five consecutive points for one complete wave, and state the domain and range for one complete wave of each. Graph each of the three functions on grids provided on the next page
