Sketch the graph of the following trigonometric functions over one period. Then, identify the domain and range, period, amplitude, vertical and phase shift (if necessary). 4. y = CSC NIXNow By 100 king at graph : Domain : 2 6 ( - 20, 0) - 5 (20+1) 42 7 where n G IL Range : ( - 00, - 1 ] 0 2, 2) 2 Period : 4 Amplitude : undefined Vertical shift : none Phase shift & 3 1 to the left. 2For this. You should know the basic y = cosecxx graph : Step 1 : 1 = Cosect 1 Basic function 3PT 27T -F 2 - Horizontal expansion by units. y = cosec 2- 7 / 2 2 2 ~ 1 Step 3 Shift the graph left by 31 unit 2 y = cosec (x+ 3x) = cosec
