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