PLEASE HELP I GIVE MEDALS (picture Inside question)
@mailtoarko try one more ... and how to do it ?
@mailtoarko how do you explain for doing a question like this next one?
well i myself saw such question for the 1st time . so here's my explanation for the next ans. you see x -> 3- i.e less than 3 .but at 3 we have a point and a graph which has values for x>3 but less than 3 we have no value for fx so limit doesn;t exist i think
what is the 3"-" for (what is the negative symbol mean
it means u should get the left limit for that
and if it's + u should get the right limit
he's right it means the left limit
so is the answer how @mailtoarko explained it ? is that the answer @amir.sat
first let me know whether the ans is correct
its a fill in answer
@amir.sat frnd wat do u think wat will be the answer of this question
for the first one if u approach the x=2 from right the y will approach 4
and for the second one if u approach the x=3 from left the y will approach -1
@amir.sat is that the limit does not exist the right answer for the second one?
not when say limit there nothing to do with the point (at x= whatever the limit says)
u just wanna know if x approach to a value what will y approach to
So the correct answer for this one is if you approach at 3 the answer is -1
no if u approach 3 from left just left the answer is -1 for right it's -4 but again as the question want the left limit the answer is -1 but remember if the question just said limit at x =3 it doesn't have any limit imean if doesn't mentioned left or right
do u know when a function have limit at a point?
a function has limit at a point just when its left and right limit are the same
ok it said lim f(x) x->3^- the - in power means get the left limit so as u see it has left limit and it's -1
in that case u shouldn't notice at the right limit
Not fully Im not sure what you saying the answer should be @amir.sat
why u say i'm wrong ?tell maybe i can help u
No I just want to know the answer .. whats the answer lol ? @amir.sat
what is the limit to this equation if it exists
read this and the simple example in it i think the third and the fourth one http://www.millersville.edu/~bikenaga/calculus/limlr/limlr.html
first one b)4 second one -1
but i suggest u to read that article
@mailtoarko what do you say?
as i said i didn't have the exact knowledge of solving this question . so i do agree with the logic of amir.sat
