Hi everyone,
It seems that entering “infinity” in WeBWorK can vary from problem to problem – but the most common versions are:
infty, -infty
infinity, -infinity
Inf, -Inf
I think the problems in this set prefer “infinity” and “-infinity”.
I was unaware of these variations – my apologies! Let me know if you are still having trouble.
