Question

need math help plz

Answer 1

So once again, use logic here. Seems tough but it really isn't. Find LHS and RHS. For LHS, first think you're at x=-1000 then -100 then -10 and then - 0.0001. You are approaching 0. Same for RHS,, first 1000 then 100 then 10 then 0.000001. It's approaching 0 again.

Answer 2

Since the RHS and LHS are approaching the same number, 0, the limit of x approaching 0 is..

Answer 3

0

Answer 4

That's the answer

Answer 5

but wait...

Answer 6

?

Answer 7

u see that 2 in the piecewise func??? what do we do with that?

Answer 8

Nothing. Try graphing the function and you'll understand it better

Answer 9

that's what's throwing me off

Answer 10

Okay there's another more algebraic way as well

Answer 11

it's just an integer... so do i just draw a dot ??? but where ? on the x or y ?

Answer 12

The limit of x approaching a for any absolute value can be broken down (theorem)

x for x>= a
-(x) for x<=a

Answer 13

So break it down here. Just because there is a do not equal sign doesn't mean you can't apply the limit

Answer 14

Recall, a function may not be defined at one point, but it still may have a limit

Answer 15

yes

Answer 16

but i wanna know how do we deal with that 2 tho ?

Answer 17

how do i graph that thingy?

Answer 18

Do you know how to graph a piece wise?

Answer 19

bro i just did...in the last quesiton

Answer 20

So then you can graph here it just like you did. 2 is defined over x=0, so it's just a point.

Answer 21

AAhh thats what i was thinking but will it be over the x or y tho?

Answer 22

will it be on the horizontal x-axis or vertical y-axis?

Answer 23

omg... stupid me.... /.- i got it

Answer 24

k thanks for the help mate... let me finish these two questions and then i'mma start a new exercise... it's about solving for limits... the fun stuff

Answer 25

thanks love :)

Answer 26
