Why do metal cooking utensils often have plastic coating on their handles?
Get a long metal spoon, and use it to stir the soup..............
What occurs is that the spoon soon becomes too hot to handle.
To make the soup less hot to handle, swap out the metal spoon for a wooden one and leave it in the boiling soup.
A wooden spoon is another poor conductor or good insulator that accomplishes the same thing. It is evident that a metal conducts heat much better than an insulator. A plastic handle, a good insulator, on such utensils reduces the conduction of heat to your handsies.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
