The given function is
![y = f(x) + k](https://img.qammunity.org/2020/formulas/mathematics/middle-school/yxl0ab2r9qlgzt1vi0wskumpo3q2vpuso9.png)
The parent function is
![y = f(x)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/4hz2zfxlqmcq6pfatrbeu6f5p0zwvmwuzs.png)
The given transformation is a a vertical translation that shifts f(x) up or down by k units.
If k is negative, the parent function shifts downwards by k units.
If k is positive, the parent function shifts upwards by k units.
The correct choice is
A) shifts the function up or Down
