GRAPH. my bad.
f(x)= 3, x<-2
f(x)=x^2+4x+4, x>-2
I sincerely hope you aren't having difficulties sketching the first one by hand! That's just a constant function.
If worst comes to worst, just pick a bunch of x values and find out f(x) and put it all on a graph.
For the second one, I'll give you a hint: It's a parabola and $\displaystyle x^2 + 4x + 4 = (x + 2)^2$
