Answer
Right shift of $\frac{\pi}{4}$
Work Step by Step
We know that
If H is any real number, then the graphs of $y = A\sin(x + H)$ and $y = A\cos (x + H)$ will have
$Horizontal\ shift = -H$, Positive means right shift, and negative meaning a left shift
so for $y = \sin (x - \frac{\pi}{4})$
$Horizontal\ shift = \frac{\pi}{4}$
i.e Right shift of $\frac{\pi}{4}$
