$5$
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.
