Hi, is it possible to do the following and get a result?:

$(\overline{(-4,1)}\cup[0,\infty)) \backslash ((-\infty,4)\cap[-1,3])$

Plotting would also be nice.

I think your image did not upload. (This makes sense, since we don't want spammy images.) Can you cut and paste text? (And now it does appear, at least for me - maybe because I edited it...)

Can you ask the question in a way that doesn't require uploading an image?

I see the image. It is the following formula: $\overline{(-4,1)} \cup [0,\infty) \setminus (-\infty,4) \cap [-1,3]$ (rendered...).

Write the expression in LaTeX between a pair of $ symbols.
