The phase shift of the function f (x) = 3 sin [5 (x - 45.)] - 1 is a) 3 units right O b) 5 units right O c) 45 right O d) 450 units left Question 2 (1 point) The period of the function f (x) = cos 3x in degrees 60 540 360 120Which of the following functions have both a vertical reflection and a horizontal reflection? Oaf (x) = sin (-2x) - 3 Obif (x ) = - cos (x) - 1 Oof ( x) = - cos |2 (x+ 360.)] Oof (x) = - sin [-5 (x - 45) ] Question 5 (1 point) The vertical shift of the function f (x) = 1. 5 cos [0. 5 (x - 90.)] + 3 ( a) 0.5 units up O b) 3 units up O c) 3 units down O d) 1.5 units down
