Answer 2

Answer 3

sorry i read wrong the question

Answer 4

it's the third

Answer 5

nope, not the third either

Answer 6

hahaha why you didn't help this girl earlier so...

Answer 7

well i don't want to just give the answer

try factoring and seeing which factors cancel

Answer 8

i got that.thanks

Answer 9

i'll become a fan of u jim_thompson

Answer 10

so, it would be the last one, then? (x+1) cancels out. Though, I don't know how to find removable discontinuity, so even if you were to find another example and show me - that'd be great! ><"

Answer 11

no, the numerator in the last one doesn't factor

Answer 12

so nothing cancels in the last one

Answer 13

but look at the first one

the denominator factors to x*(x-1)

notice how the 'x' terms cancel leaving you with 5/(x-1)

Answer 14

so the removable discontinuity is x = 0

Answer 15

good answer jim

Answer 16

Oh..
