As below

Explanation:

Standard form of sine function is y = A sin (Bx - C) + D

Given y = 2 sin(-2x + pi) + 1

A = 2, B = -2, C = -pi, D = 1

Amplitude = |A| = 2

"Period " = (2pi) / |B| = (2pi) / 2 = pi

"Phase Shift " = -C / B = -pi / -2 = pi/2, " " pi/2 " to the RIGHT"

"Vertical Shift " = D = 1
