The phase shift of a sine function of the form $y = a \sin(b(x - c))$ is $c$ units to the right if $c > 0$. Here, $c = \frac{\pi}{4}$, so the phase shift is $\frac{\pi}{4}$ units to the right.

Find the Phase Shift of the Function y=5sin⁡(x−π4)y = 5 \sin \left( x - \frac { \pi } { 4 } \right)y=5sin(x−4π​)
