Which of the following trigonometric equations meets the criteria given? amplitude = 3, period = , phase shift = y = 3sin(x-) y = 3sin2(x-) y = 3sin2(x-2)

y = 3sin2(x - pi)

Step-by-step explanation:

The number in front of the trigonometric value (sin, cos, tan, etc.) indicates the amplitude. If the period is pi then the value in front of x must be 2, because frequency (in other words, the period) is determined by the equation 2pi/B, where the value in front of (x) is B. And if the phase shift is pi, or positive pi, then the corresponding equation must be (x - pi) because it's always the opposite.
