Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

it means u should get the left limit for that

Answer 8

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

Answer 9

he's right it means the left limit

Answer 10

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

Answer 11

first let me know whether the ans is correct

Answer 12

its a fill in answer

Answer 13

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

Answer 14

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

Answer 15

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

Answer 16

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

Answer 17

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

Answer 18

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

Answer 19

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

Answer 20

right?

Answer 21

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

Answer 22

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

Answer 23

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

Answer 24

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

Answer 25

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

Answer 26

u understand me?

Answer 27

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

Answer 28

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

Answer 29

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