Proving the Limit of Zero Using Epsilon-Delta Method

[savtaylor2010]

Epsilon-Delta proof of zero??

Homework Statement

Write an epsilon delta proof for the lim_{x$\rightarrow$2} 0 = 0.

The Attempt at a Solution

This is for my discrete math class. I know how to do limit proofs with a variable, like x or x², but it seems that this is obvious that the limit approaching zero is zero. It is so easy, that it is hard for me to use epsilon and delta to prove. I don't know really where to start for this one. I would appreciate some hints and help!

It might help to call f(x) = 0. Write down the definition as you would with f(x) and L and replace f(x) and L by 0.

Start by choosing an epsilon maybe let epsilon equal something really close to 0 like 0.2

and assume that x-2< alpha . so that you can so that 0<ε .

hint: the proof is eactly the same if you replace 0 by c, where c is any constant. that is, if you replace the function f(x) = 0 with g(x) = c, the same argument works for both (the "delta" is really easy to find, for any "epsilon").
