Answer
horizontal;
right
Work Step by Step
RECALL:
The graph of the function $y=f(x-h)$ involves a horizontal shift of $h$ units to the right of the parent function $f(x)$ when $h\gt0$ and $|h|$ units to the left when $h\lt0$.
Thus, the given function, where $h=2$, involves a $2$-unit shift to the right of the parent function $f(x)$.
Therefore, the missing expressions in the givens statements are (in order):
horizontal;
right
