Question

lim as w->-1

w^2+7w+7/w^2-4w-5

help

Answer 1

\[\lim_{w \rightarrow -1}\frac{ w^2 + 7w + 7 }{ w^2 -4w -5 }\]

Answer 2

The simplest way to solve this is by substituting all w's by -1 because the limit of w is approaching -1.

Answer 3

i know but the denominator will be 0 and it will be undefined

Answer 4

You take the two sided limits and find each limit

Answer 5

You will get one as + infinity
The other as -infinity
The final answer of limit: does not exist
