# Plot Functionsfunctions over Different Domainsdifferent domains with Legendlegend

I have two functions which I'd like to plot over different domains, and combine them into a single plot, with a legend included. If it weren't for the legend, I'd simply use Show. However, I have issues with Mathematica's new ShowLegend even in the most trivial case, so I'm not sure quite how to go about this. There are a few posts about using ShowLegend within Show but I had trouble making sense of them, and I'm wondering if my simple case, there's an easier way. An example that will suffice is

F[x_] := Sqrt[4 - x^2]; G[x_] := 9 - x^2; Plot[F[x], {x, 0, 2}] Plot[G[x], {x, 0, 3}]

F[x_] := Sqrt[4 - x^2];
G[x_] := 9 - x^2;
Plot[F[x], {x, 0, 2}]
Plot[G[x], {x, 0, 3}]


with the resulting plot being over the full range {x, 0 ,3}.
