Please explain this in an easy way to understand thank you

When a function's y-value approaches either +00 or -00 as x approaches c, the Limit Does Not Exist (DNE). If it is possible, we also state the Limit is either equal to +00 or -0o before backing this up with DNE.
1. Under which circumstances for an infinite limit could you ONLY state limf(x) = DNE and not say that the Limit is also egual to either +00 or -00.
2. In your explanation, describe what must be happening for the following one-sided limits:
lim f(x) and Ilim f(x).
X+ c-
x + c+
3. Finally, provide an example function that exhibits these properties at x = 2.
