Functions and graphs...

I am having trouble with this one, looked everywhere in the book but did not find what i was looking for. I understand what i have to do but not sure how to do it.

"The graph of f(x) is given below(i will describe it for you).
Use the graph of the given function F to sketch the graph of the function g(x)=f(-x-1)+2"

graph of f(x).... when x=-3, y=-3
x=-2, y=-1
x=-1, y=1
x=0, y=3
x=1, y=3
x=2, y=3
x=3, y=3
x=4, y=1

thanks in advance
