Question

Evaluate the limit:
Limit of the function (7/x - (7 - |x|)) as x approaches 0 from the left side (0-)

Answer 1

If you are looking at it from the left, then x will be less than 0. Then it will be negative, so if you put in that, you get:

(7/x - (-7/x)
= (7/x + 7/x)
= 14/x
taking the limit of function (14/x) as x approaches 0 from the left side DNE right?

Answer 2

But then when I enter this answer "DNE" into my electronic assignment, it says that this answer is wrong.

Answer 3

\[\frac{7}{x} - \left( 7 - |x|\right)\]?

Answer 4

No it is:
(7/x) - (7/|x|)
