$$\\y=\sqrt[3]{x+4}-3\\\\
$this is how I think of these$\\\\
(y+3)=\sqrt[3]{(x+4)}$$

 

now

solve y+3=0  the answer is y=-3    so got down 3 units

solve x+4=0  the answer is x=-4   so go left 4 units

Notice how I used the brackets.  This is important to get the grouping correct.

I do not think everyone thinks of it like this but it works well for me.
