Solution:
Given:
The parent function is;
[tex]y=sin\text{ }x[/tex]
[tex]\begin{gathered} The\text{ transformation that will move the sine function left by }\frac{\pi}{4}\text{ will be;} \\ \\ This\text{ indicates a horizontal shift.} \\ Hence, \\ y=sin(x+\frac{\pi}{4}) \end{gathered}[/tex]
Therefore, the transformed function is;
[tex]y=sin(x+\frac{\pi}{4})[/tex]
