As below.

Explanation:

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

Given : y = - sin (3x - (3pi)/3) + 4

A = -1, B = 3, C = pi, D = 4

Amplitude = |A| = |-1| = 1

"Period " = (2pi) / |B| = (2pi)/3

"Phase Shift " = (-C) / B = (-(3pi)/3) / 3 = -pi, color(red)(pi " to the LEFT"

"Vertical Shift " = D = 4

graph{- sin(3x - pi) + 4 [-10, 10, -5, 5]}
