Can anyone help and explain to me for this......??
The same does not work for negative infinity since inf x 0 is undefined.
The trick here is to express the function as a fraction of two terms such that inf x 0 becomes "inf / inf" or "0 / 0" since the inverse of 0 is technically inf and vice versa.
Now that we get either form, we can then use the L Hospital rule until we no longer get either form.
Sadly, only one of the fraction forms work because the L Hospital application would end at some point, whereas in the other form, there will never be an end.
