Show function seems to be broken [closed]

I read the thread How to make the Show function work in this case?. I think I have the same problem as discussed there. But when I try the to evaluate

Show[Plot[x^2, {x, 2, 10}], Plot[1 – x, {x, 1, -10}],
PlotRange -> All]

it doesn’t work. The output:

.

How can I fix it?

Update:
This comes afterClear[“*”, All];.
Clear[“*”, All];
Show[Plot[x^2, {x, 2, 10}], Plot[1 – x, {x, 1, -10}],
PlotRange -> All] makes it failed.

Clear[“*”] clears every symbol found on $ContextPath which is not Protected. So many System` symbols too…

Moreover, unless you want to double clear System`All, Clear[“*”, All] is made up syntax.

What you probably want is Clear[“Global`*”] or ClearAll[“Global`*”]

Ergo, Show appeared to be broken because the OP broke it.
