would (x)/(x^2-4) be a discontinuity

do you mean it would be contiuous if the rational function was a polynomial divied by a constant like for ex. (x+1)/3. but wouldn't that give you a linear function

so does that mean all rational functions are discontiuous.

ok then how would you compare that with a function that is not discontinuous like 1/(x+3)

wat i ment was it dosent cancel out or anything

sorry but i still don't get it, its not like we have a denominator of zero

so you are saying that a would be the constant. like in my example if we factor x^2+x-6 we get (x-2)(x+3), so how would that be undefined

at x=2,-3. i understand that but when you say x=a what do u mean by that. can you show me a variable formula (using a, b and c) that would better explain this

i am looking for a simple definition of discontinuity using the example 3/(x^2+x-6)

Thanks for the help, and just to be sure, the range is always expressed as y \neq ...

positve infinity or y > 0

i got that from punching in random x values on my graphing calc. (10, 20, 30) and as they got bigger the y values got smaller but never reached zero.

infinity? sorry but i just don't get this

i think you can make it zero, but can you please explain

sorry i am still in math 20 and we didnt take interval notation yet
