lemme post a quick template of some help



so f(x) - k, is simply appending a constant "k", and thus is a vertical shift by
k units.
f(x+h) is changing whatever "x" was to "x+h", and therefore is shifting the function to the left by
h units.
f(x-h), is about the same as before, but is doing a horizontal shift to the right by
h units.
