What does it mean when it says y approaches -5^+?

i understand why it approaches -5 but what is the + for and when are you supposed to use ot
acoustic elbow
means from the right side
because the right side is positive and the left side is negative

So i graphed the function and it shows this
so if x approaches -inf and there is an asymptote then y approaches the asymptote and you raise it to +?
Now ive graphed the same thing except reflected it across the y axis so does that mean when x approaches infinity y approaches 5^- because its coming from the left side

you're not raising it to +, the + is just notation meaning that the limit is coming from the positive direction

I think this one is still -5^+ because y is approaching -5 from the positive direction
I usually see the direction attached to the function input x instead of y though

when you mean positive direction is it in terms of the x values or y values?
pastel furnace
in terms of the value the + or - is attached to so I'd expect the y-> -5+ to mean y approaches -5 from the positive direction
barren kite
so y values?
pastel furnace
it depends on what the + or - is attached to
if it said x-> -5^+ I would read it as x approaches -5 from the positive direction (the right)
barren kite
so if the + or - is attached to the y then its in terms of y and if the + or - is attached to the x then it is in terms of x?
