Find the phase shift of the function.
-$$y = \sin \left( x + \frac { \pi } { 4 } \right)$$
A) $\frac { \pi } { 4 }$ units to the right
B) $\frac { \pi } { 4 }$ units up
C) $\frac { \pi } { 4 }$ units to the left
D) $\frac { \pi } { 4 }$ units down

Quizplus · Accepted Answer

The phase shift of the function $y = \sin(x + \frac{\pi}{4})$ is $-\frac{\pi}{4}$, which means the graph shifts $\frac{\pi}{4}$ units to the left.

Find the Phase Shift of the Function y=sin⁡(x+π4)y = \sin \left( x + \frac { \pi } { 4 } \right)y=sin(x+4π​)
