ANSWER
[tex]undefined[/tex]EXPLANATION
The given function is the function of a vertical line. It is a straight line.
All straight-line graphs have a linear function and the parent function of all linear functions is:
[tex]y=x[/tex]Hence, the parent function of the given function is:
[tex]y=x[/tex]We want to identify the transformation for the function.
