Extreme Value Theorem true for constants?

Click For Summary

Discussion Overview

The discussion revolves around the application of the extreme value theorem to constant functions, exploring whether it is reasonable to consider constants as having both maximum and minimum values over a closed interval.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant expresses skepticism about the extreme value theorem applying to constant functions, questioning the validity of considering every point as both a maximum and minimum.
  • Another participant points out that constant functions are continuous, asking for clarification on the initial skepticism.
  • A participant reiterates their discomfort with the theorem, stating that it feels unsatisfactory to have every point be a minimum and maximum for constant functions.
  • Further discussion reveals that while the theorem states there must be a minimum and maximum, these values can be the same in the case of constant functions.
  • Participants define maximum and minimum values in the context of constant functions, acknowledging that technically they exist but expressing dissatisfaction with the concept.

Areas of Agreement / Disagreement

Participants generally disagree on the satisfaction of the extreme value theorem's application to constant functions, with some accepting the theorem's logic while others find it unappealing.

Contextual Notes

Participants express personal feelings about the theorem rather than focusing solely on its mathematical validity, indicating a subjective interpretation of the definitions involved.

My textbook says the extreme value theorem is true for constants but I don't buy it. I mean I suppose that every value over a closed interval for a constant would be a maximum and a minimum technically but it seems like BS to me. Can anyone explain why this BS is true?

Constant functions are continuous, I don't really understand what your issue is. Can you elaborate about why this is bs?
 
No, my problem is the extreme value theorem says that for a continuous function on a closed interval there will be a minimum and maximum value. My complaint with that is for a constant every point is a minimum and a maximum and I just think that is pretty lame so I'm mad.

Well, okay then.
 
Well thanks for your answer, my problem isn't with my understanding of it I just don't really like it. However, your point about the theorem saying that the function must simply have a min and max makes sense, I suppose that the min and max don't have to be different and not be at every point; I still don't like it though.
 
As a follow up question, how would you define the maximum and minimum of a function? Do you know the definition or do you just find it is not pleasing to how one thinks about maximum and minimum?
 
Max= highest value the function reaches
Min= lowest value a function reaches

So for a constant yes they would have both technically. Like I said I just think it's poop.
 
But I do see what you're saying and I appreciate your logic. Thank you.
 
Hmm, Alright.
