    It’s been a while… but isn’t that negative?

    Or is there some default given of which side it’s approaching from.

      I have a BA in Mathematics. The limit is indeed determined by the direction you approach the limiting value.

      When given without specification, the limit is implied to come from the left, meaning it increases towards the limiting value, which is why you see +inf.

        Yeah but then it should be negative infinite, cause if x<8 the fraction is negative.

      I think it is not defined. It has a limes from the left (- inf) and limes from the right (+ inf) but no two-sided limes.

      Edit: wolframalpha agrees but I don’t know for sure

      It should be +/-∞

      Minus or plus depending on the side from which you approach the limes.

      I took a screenshot and put it in a word doc and embedded that in a excel sheet and sent it in an email…

    That’s a ChatGPT kind of answer. A pattern is recognized, but the meaning isn’t understood.
