i got discontinuity at x=-1, x=0, x=1
removeable at x=1, jump at x=-1, is it infinite at x=0?
and my reasoning behind x=1 was that a limit from the left and right as x-> 1 exists and a limit exists but since there is a hole at (1,1) f(1) does not exist therefore it is a removeable discontinuity
reasoning behind x=1 was that limit from the left and right were not equal and a limit does not exist when x-> -1
which produces jump discontinuity
idk how 2 prove infinite discontinuity tho or if that even is an infinite discontiunity or if its a jump
cuz its not like all the infinite discontinuities i've seen where the limit from left and right is infinitely approaching 0
from the left it's infinitely approaching 0 but from the right it's going towards a hole at like roughly (0,3)
so if anyone could double check my reasoning and answers for x=1 and x=-1 as well as explain to me x=0 i'd appreciate it 🫡
#calc 1 discontinuity help

Yeah X=1 and -1 look good
ok cool n then x=0
And for an infinite discontinuity if the limit doesn’t exist for either side
Nah from the left as X approaches 0
Y approaches infinity
So the limit doesn’t exist
So it’s an infinite discontinuity
because there's no limit from the left side
and none from the right side because of the hole?
Yeah for the first one
From the right it approaches 3
Limits is like saying what does it get close to
So since from the right it gets close to 3
The limit from the right is three
But from the left since it goes to infinity it doesn’t get close to anything so there is no limit
so it would be the top one
these were the notes i took for each discontinuity
i didnt get any for infinite and i dont really get what i wrote for removeable
Both are right
Like the names are kind of intuitive
Removable is like you grab the point and put it somewhere else
is there like a clear set of conditions somewhere for each discontinuity using the formal definition if discontinutiy 😔
Hence you “remove” it
A jump is well where you jump XD
And infinite is where one of the limits is infinity
ok so for x=0 its an infinite discontinutiy because when takign the limit from the left we're given infinity which means it is an infinite discontinuity
Continuous functions are of utmost importance in mathematics, functions and applications. However, not all functions are continuous. If a function is not continuous at a point in its domain, one says that it has a discontinuity there. The set of all points of discontinuity of a function may be a discrete set, a dense set, or even the entire doma...
This is pretty good honestly with some examples
Yeah
so whenever i get limit = plus or minus infinity/DNE then its infinite discontinutiy
removeable happens when i get uh
a limit exists but L does NOT equal f(x)
and jump happens when the limit from left and right differ therefore lim f(x) doesnt exist
that sound right?
Yeah that sounds awesome
sweet ty
You’re welcome mate have a good one
