Can you plot straight lines and parabolas? If so, plot the graph of $y=x+1$. It has slope $1$ and $y$ intercept $1$. Notice that the part of your graph where $x < -1$ agrees with your graph, so just keep that part. Similarly, do the other two parts.

Yes, that does it. I feel too dumb right now. Ah, thank you.
