What were your results?Thats what I did. I got to x < 4 and x > 4
After that, what do I do?
My results were -1What were your results?
What is |4 - x| / (x - 4) when x < 4?
What is |4 - x| / (x - 4) when x > 4?
For both cases? If so, the limit would be -1.My results were -1
I did???For both cases? If so, the limit would be -1.
However, you made a mistake in one of the cases.
You did, if you got -1 for both cases.I did???
Correct, the limit from the left doesn't equal the limit from the right, so the overall limit does not exist.Ahhh...So, then my calc comes out as -1 and 1, therefore it does not equal so its undefined?
