Question

What is the limit of square root of (5 - x) as x approaches infinity?

Answer 1

`Lim_(x->oo)sqrt(5-x)=ioo`

The limit does not exist in the real number domain.

Explanation:

.

`Lim_(x->oo)sqrt(5-x)=Lim_(x->oo)sqrt((-1)(x-5))=`

`Lim_(x->oo)((sqrt(-1))(sqrt(x-5)))=Lim_(x->oo)(isqrt(x-5))=ioo`
