Dear all,

I just want to ask and satisfy my curiosity, I see this

I wonder whether my plotting is correct or not (how to show the - \frac{1}{x-5} graph only the one below x-axis?):

```
using Plots, LaTeXStrings, Plots.PlotMeasures
gr()
f(x) = -(x-1)^(2)
g(x) = -1/(x-5)
plot(f,-10,10, xticks=false, xlims=(-13,13), ylims=(-33,33),
bottom_margin = 10mm, label=L"f(x) = -(x-1)^{2} ", framestyle = :zerolines,
legend=:outerright)
plot!(g,-10,10, xticks=false, xlims=(-13,13), ylims=(-13,13),
bottom_margin = 10mm, label=L"f(x) = - \frac{1}{x-5} ", framestyle = :zerolines,
legend=:outerright)
scatter!([-1], [f(-1)], color = "red", label=L"(-1,f(-1))", markersize = 2)
scatter!([3], [f(3)], color = "green", label=L"(3,f(3))", markersize = 2)
annotate!([(0.5,0, (L"|", 11, :black))])
annotate!([(1.5,0, (L"|", 11, :black))])
annotate!([(0.5,-1.5, (L"a", 11, :black))])
annotate!([(1.5,-1.5, (L"b", 11, :black))])
```
