How do you tell if a bond is polar or nonpolar?
Well if it is an heteronuclear bond, i.e. the bond is NECESSARILY polar....

A bond is polar if there is a significant difference in electronegativity between the atoms involved, resulting in an uneven distribution of electron density. A bond is nonpolar if the electronegativity difference between the atoms is negligible or nonexistent, resulting in an even distribution of electron density. You can determine the polarity of a bond by comparing the electronegativities of the atoms involved using a periodic table or electronegativity chart. If the electronegativity difference is greater than 0.4, the bond is typically considered polar. If the difference is less than 0.4, the bond is usually considered nonpolar.

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.
