What is the domain of the function #f(x)=(3x^2)/(x^2-49)#?
The domain of a function is the set of the values in which you can calculate the function itself.
The problem of finding the domain of a functions is due to the fact that not every function "accepts" every real number as an input.

The domain of the function ( f(x) = \frac{3x^2}{x^2 - 49} ) is all real numbers except ( x = 7 ) and ( x = -7 ), because the denominator cannot be zero.

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.
