Feel weird correcting a meme, but that should be f(x)-L where x is between x_0 - delta and x_0 + delta. As written it looks like a definition that would only work for monotone functions.
Lemmy actually supports proper subscript (though not not clients do). Surround with tildes (single tildes, rather than the double tildes of strike-through).
x0 - δ is x~0~ - δ
Edit: and now, at least on Jerboa, the code block version is displaying incorrectly, although it now does support the actual subscript…
