ANSWER

A) shifts the function up or Down

EXPLANATION

The given function is

[tex]y = f(x) + k[/tex]

The parent function is

[tex]y = f(x)[/tex]

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
