One-sided limits

[Sniles]

I really could use some help on this one! I don't want it solved, I just need help getting it started!

Find lim(x-> -3) l x+3 l if it exists. If it doesn’t, explain why![/tex]

To get started, graph f(x) = |x + 3|. Pay particular attention to the graph (in particular, the slopes of the graph) on either side of x = -3.
