I don't get why $\displaystyle y=\left | x+c \right |$ should shift the graph to the left. When I try to reason it out, I see that we are adding a value to x, thus making it bigger, shouldn't we be moving on the number line to the right?? I can simply memorize this one rule, but I am trying to understand it rather than simply memorize it. Thanks in advance.

Unfortunately, I do not see where you are leading...

Can you elaborate?

Can anyone else shed some light on this?
