    Because the coefficient of x = 2pi/period so 3=2pi/period so 3(period) = 2pi and the period = 2/3 pi instead of the normal 2pi

    okay so f it was like (1/3 x - ⫪/4) then the answer would be a horizontal stretch by 3 ?

    you would plug the coefficient of x into the equation I gave you and solve. coefficient of x = 2pi/period
