The graph or y amplitude = 2. The amplitude of y = 3 sin x is period is and period and the 3. The period of y = 4 sin 2x is X-values for the five key points are x1 ,so the and X2 = X5 = X3 X4 = 4. The graph of y = A sin(Bx - C) has phase If this phase shift is positive, the graph If this phase shift of y = A sin Bx is shifted to the shift is negative, the graph of y = A sin Bx is shifted to the EXERCISE SET 4.5 Practice Exercises In Exercises 1-6, determine the amplitude of each function.
