Recall that
limx⟶cf(x)=L
means:
For all ϵ>0 there is a δ>0 such that for all x satisfying 0<|x−c|<δ we have that |f(x)−L|<ϵ.
What if the limit does not equal L? Think about what the means in ϵ,δ language.
Consider the following phrases:
1. ϵ>0
2. δ>0
3. 0<|x−c|<δ
4. |f(x)−L|>ϵ
5. but
6. such that for all
7. there is some
8. there is some x such that
Order these statements so that they form a rigorous assertion that
limx⟶cf(x)≠L
and enter their reference numbers in the appropriate sequence in these boxes:
