Answer
The given function is
.* **Amplitude:** The amplitude is the absolute value of the coefficient of the sine function. In this case, the amplitude is
.* **Period:** The period of a sine function is given by
, where
is the coefficient of
. In this case,
, so the period is
.* **Phase Shift:** The phase shift is determined by the term inside the sine function. We rewrite the argument of the sine function as
. The phase shift is given by the value subtracted from
. In this case, it is
. Since it is subtracted, the phase shift is to the *right* by
.* **Vertical Shift:** The vertical shift is the constant term added to the sine function. In this case, the vertical shift is 3. Since it is positive, the shift is *up* by 3.Therefore, the correct answer is:a. Amplitude: 9Period:
Phase shift: Right
Vert. shift: Up 3Final Answer: The final answer is
