Question

Why does this not exist? I thought if you plugged in infinity, you would just get infinity. Do you not plug in infinity?

Answer 1

See below

Explanation:

It does not exist because the

`(-1)^x`

doesn't tend to some value it just loop around

`-1, 1`

for ever

it exist when we have

`\lim_(x\rightarrow \infty)[((1)/(x))]`

there when the value of x increasing the fractions tends to 0

so we can say that when x approaches infinity the value is 0.

Tell me if i haven't made myself clear
