"WebThe Extreme value theorem requires a closed interval. You cannot have a closed bound of ±∞ because ∞ is never a value that can actually be reached. Thus, a bound of infinity must be an open bound. So, it is (−∞, +∞), it cannot be [−∞, +∞]. Thus, the requirements for the Extreme value theorem are not met, so it does not apply.
