Homework Statement
Given a function f:R\rightarrow R and a number L,write down a definition of the statement
\lim_{x\rightarrow-\infty}f(x)=L
The Attempt at a Solution
Is it just \lim_{x\rightarrow-\infty}f(x)=\lim_{x\rightarrow\infty}f(-x) ?
and definition is
for \forall \epsilon>0 \exists N such that \forall n>N
we have |f(-x)-L|<\epsilon
