It has a phase shift of pi to the right.
pi 3 3 pi pi/3 those are the choices
The phase shift is denoted by the value that comes after x. Since in this case (3x-pi) and pi is negative, it means right. On the other hand, if the pi was to be positive it would be to the left.
Therefore this equation has a phase shift of pi to the right.
Let me know if you have any questions.
i dont understand like any of this.
ok. Let's use a standard formula y=-cos(x-c) C is the horizontal translation, or otherwise referred to as the phase shift. If C is negative, then the phase shift is to the right. But if it's positive then it's to the left.
but what is the answer from choices and how do you get it like how do you know which one is right
the phase shift is pi. Therefore you would pick the first option.
okay if it were be the other how would it be different?
the first option was wrong
Then I belive the question must have been worded wrong.
If one's looking for phase shift then it would be pi, and pi alone disregarding the direction which is to the right, since it's negative.
i copied and pasted it. Sometimes i think the thing just has to wrong answer honestly
