Question

need help with limit graph and q's

Answer 1

can you see it

Answer 2

a) = -1
b = 2

Answer 3

hmmm I don't think that is right a or b

Answer 4

what do you think it is

Answer 5

limit is asking what is the y value as x gets closer to -3 ...a) is asking what is y becoming as x turns into three from the left side. That arrow is definitely not pointing to -1. b) is asking the same thing from the right side that arrow is not pointing at 2.

Answer 6

x turns to negative 3

Answer 7

so it should be -1 right?

Answer 8

-3 looks like a vertical asymptote to me...which x=-3 are you looking at? maybe the graph you posted and the one im seeing are different?

Answer 9

oooh my mistake

Answer 10

so - inf

Answer 11

for a)

Answer 12

3 for b?

Answer 13

yes but depending on how your teacher/book are looking at it they may say that the limit is undefined too

if you start at x = 0 and move left towards x=-3 what happens to the line with the arrow?

Answer 14

yeah undefined also

Answer 15

=) that one is heading to +oo

Answer 16

so I know you have c) nailed

Answer 17

and d) for that matter

Answer 18

c = DNE

Answer 19

and neg inf

Answer 20

d = 3

Answer 21

oh so close....c) is saying if you approach from either direction...so it is + and - infinity depending which side of the line you are on....so undefined probably best.

for d) what is y when x=-3?

Answer 22

d = 3 right

Answer 23

no =) the arrowy lines don't point at 3 they point at?

-oo and +oo.....so .......undefined the lines dont cross x=-3 at all

Answer 24

alright the next few are tough

Answer 25

is it all .5?

Answer 26

e-h

Answer 27

uh oh I thought there were getting easier...

all good

Answer 28

i - L have a trick to them

Answer 29

wait so e- h = .5 right?

Answer 30

indeed you are correct

Answer 31

cool

Answer 32

i = 1

Answer 33

f = 1

Answer 34

it is always easier when the limits exist

i=1 is correct

Answer 35

well j anyway =)

Answer 36

right haha

Answer 37

k also 1

Answer 38

you on a roll now

Answer 39

j = dne

Answer 40

woot

Answer 41

j should exist; its a onesided limit

Answer 42

nah it cant its asking for the value at f(0)

Answer 43

oh right yeah

Answer 44

j. lim{x ->0+} = ?? its goes to 1

Answer 45

lets move onto m

Answer 46

aaak i didnt pay attention to you going back to j I read that as an L

Answer 47

yep we already got that

Answer 48

yep me 2

Answer 49

okies I am at M

Answer 50

m = 4?

Answer 51

f = 4

Answer 52

sorry n = 4

Answer 53

m=5 if the graph is right

Answer 54

m != 4 keep in mind the axis are in a funny spot

Answer 55

yeah

Answer 56

x=1 looks a lot like that vertical asymptote at -3 to me

Answer 57

m-p = 4

Answer 58

I think you are looking at the wrong x=1

Answer 59

oh hi mistre!

Answer 60

yep

Answer 61

m= - inf

Answer 62

I think so too

Answer 63

n = - inf

Answer 64

now we back on track

Answer 65

o = - inf

Answer 66

o. oh oh yeah

Answer 67

and p = dne

Answer 68

=) you got it now

Answer 69

only q 2 p 2 go

Answer 70

q = - .5

Answer 71

or maybe that should be a t who built this chart anyway?

Answer 72

r = -.5

Answer 73

yeah really weird graph

Answer 74

I buy q=-.5 and r too for that matter

Answer 75

s = -.5

Answer 76

yay

Answer 77

q as well -.5

Answer 78

t) i mean

Answer 79

ding you have reached the next level....hehe alphabetically challenged homework

Answer 80

new graph hold on second

Answer 81

do you see it

Answer 82

limx→2+f(x) =5≠limx→2−f(x)=2

Answer 83

let me print it out standby

Answer 84

we need 4 answers

Answer 85

and im playing world of warcraft too....semester ended monday for me =)

Answer 86

haha

Answer 87

are you in hs or college?

Answer 88

college...again ....

Answer 89

nice pass time hit the ladies up instead ;)

Answer 90

but what would my wife think?

Answer 91

ah never mind then

Answer 92

f(2) exists (infact f(2) = 4

Answer 93

we need 4 answers

Answer 94

f(x) is continuous at 2 i think jump continutity

Answer 95

so far
a)f(x) is continuous at 2 i think jump continutity
b) f(2) exists (infact f(2) = 4
c) f(2) = limit x->2 F(x)

Answer 96

jump continuity is the opposite of continuous though

Answer 97

so is it continuous?
