ANSWER
Vertical shift: 2 units up.
EXPLANATION
The parent function is
[tex]y = |x| [/tex]
The transformation applied to this function is of the form:
[tex]y = |x| + k[/tex]
This is a vertical shift of the parent function by k units, upwards.
Hence,
[tex]y = |x| + 2[/tex]
is a translation of the parent function up by 2 units.
