#### Answer

$5$

#### Work Step by Step

RECALL:
The graph of the function $y=f(x)+k$ involves a vertical shift of $|k|$ units (upward when $k$ is positive, downward when $k$ is negative) of the parent function $f(x)$.
The parent function of the given function is $y=x^2$.
The given function has a $k=5$.
Thus, the graph of the given function involves a 5 unit shift upwnward of its parent function.
