@mailtoarko how do you explain for doing a question like this next one?

- anonymous

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

- anonymous

what is the 3"-" for (what is the negative symbol mean

- anonymous

it means u should get the left limit for that

- anonymous

and if it's + u should get the right limit

- anonymous

he's right it means the left limit

- anonymous

so is the answer how @mailtoarko explained it ? is that the answer @amir.sat

- anonymous

first let me know whether the ans is correct

- anonymous

its a fill in answer

- anonymous

@amir.sat frnd wat do u think wat will be the answer of this question

- anonymous

for the first one if u approach the x=2 from right the y will approach 4

- anonymous

and for the second one if u approach the x=3 from left the y will approach -1

- anonymous

@amir.sat is that the limit does not exist the right answer for the second one?

- anonymous

not when say limit there nothing to do with the point (at x= whatever the limit says)

- anonymous

u just wanna know if x approach to a value what will y approach to

- anonymous

So the correct answer for this one is if you approach at 3 the answer is -1

- anonymous

right?

- anonymous

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

- anonymous

do u know when a function have limit at a point?

- anonymous

a function has limit at a point just when its left and right limit are the same

- anonymous

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

- anonymous

in that case u shouldn't notice at the right limit

- anonymous

u understand me?

- anonymous

Not fully Im not sure what you saying the answer should be @amir.sat

- anonymous

why u say i'm wrong ?tell maybe i can help u

- anonymous

No I just want to know the answer .. whats the answer lol ? @amir.sat

- anonymous

what is the limit to this equation if it exists

- anonymous

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

- anonymous

first one b)4
second one -1

- anonymous

but i suggest u to read that article

- anonymous

@mailtoarko what do you say?

- anonymous

as i said i didn't have the exact knowledge of solving this question . so i do agree with the logic of amir.sat
