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.
Ah, I misread the - as a +. You're correct! Sorry, I just woke up and am in the middle of my morning doomscrolling sesh
Conveniently modeled with the same limit.
Though I'm not sure what negative doom is and what happens when it approaches infinity.
