right; $4$
RECALL: The function $y=f(x-h)$ involves a horizontal shift of either $h$ units to the right of the parent function $f(x)$ when $h \gt 0$ or $|h|$ units to the left when $h\lt0$. The given function has $h=4$. Thus, its graph involves a 4 unit-shift to the right of the parent function $y=x^2$. Therefore, the missing expressions in the given statements are: right; $4$
