Look at the picture.
(x, y) → (x + 2, y)
Translate the graph of f(x) 2 units right.
-------------------------------------------------------------
(x, y) → (x, y + n) - translate the graph n units up
(x, y) → (x, y - n) - translate the graph n units down
(x, y) → (x - n, y) - translate the graph n units left
(x, y) → (x + n, y) - translate the graph n units right
