Give an equation for a transformed sine function with an amplitude of 2, a period of 2, a phase shift of 2 rad to the right, and a vertical translation of 1 unit down. O a) y= 0.5 sin [ 0.8 x(x - 1.5) ] - 1 O b) y= 0.5 sin[ 0.8(x + 1.5) ] - 1 O c) y= 0.5 sin[ 0.8 (x - 1.5) ] - 1 O d) y= 0.5 sin [ 0.8x(x + 1.5) ] - 1
