All i need to know is what my limit is at x=1 or if the limit even exists.axmls said:You're correct, but perhaps you should go back and read about what it means for a limit to equal a value. Does it matter what happens to the function at the point you're approaching?
Which you will learn if you follow axmls's suggestion.AllanW said:All i need to know is what my limit is at x=1 or if the limit even exists.
The way things work here at PF is that we help you arrive at an answer, but we won't just give it to you.axmls said:perhaps you should go back and read about what it means for a limit to equal a value. Does it matter what happens to the function at the point you're approaching?
Okay, would i be correct if i said the limit for x at 1 would be -2?Mark44 said:Which you will learn if you follow axmls's suggestion.

Yes. Do you understand why?AllanW said:Okay, would i be correct if i said the limit for x at 1 would be -2?
I believe it because the limits approaching 1 from the left and right side is -2, what i don't understand is if and where the 'f(x)=3 when x=1' comes into playMark44 said:Yes. Do you understand why?
What does your book have for the definition of the limit of a function at some number?AllanW said:I believe it because the limits approaching 1 from the left and right side is -2, what i don't understand is if and where the 'f(x)=3 when x=1' comes into play
