x < ∞ means that "x is less than infinity."
This inequality seems illogical.
Ignore this problem.
To my knowledge, the infinity symbol -- ∞ -- has never appeared on the GMAT.

I agree with Mitch.
We can simplify the inequality as x < 2
What's the source of this question?
Cheers,
Brent

Is it just me, or did the prompt disappear? I can't see the original question.

Brent, you're a wizard!
Having ∞ and -∞ as the bounds looks janky to me: the GMAT would simply give -2 < x, not -2 < x < ∞.
