T(x) = a * sin k(x + c) ) +d 1. State the transformation to the graph of either y - sin x ory - cos x that has occurred to result in each sinusoidal function. a) y = 3 cos x COS & - 6 b) y - sin (x - 50) d) 3 - sin (5x) D y = cos (x + 20) 2. Each sinusoidal function below has undergone one transformation that has affected either the period, amplitude, or equation of the axis. In each determine which characteristic has been changed and indicate incvalue. @) y = sin x + 2 c) y = cos(8.x) e) y - 0.25 cos 3 b) y = 4 sin x d) y = sin(2x + 30") f) y = sin(0.54) 3. Which two of these transformations do not affect the period, amplitude, or equation of the axis of a sinusoidal function? a) reflection in the x-axis d) horizontal stretch/ b) vertical stretch/vertical compression horizontal compression ( ) vertical translation horizontal translation
