Suppose y = f (x ) is function and c > 0 is a constant.
The graph of y = f (x ) + c is the graph of y = f (x ) shifted up
c units.
The graph of y = f (x ) − c is the graph of y = f (x ) shifted
down c units.
The graph of y = f (x − c ) is the graph of y = f (x ) shifted
right c units.
The graph of y = f (x + c ) is the graph of y = f (x ) shifted
left c units.
