Here is a guess that you do not mean what you wrote but mean this instead:
f(x)=(3x^2)/(x^2-49) as text
OR
in rendered typesetting.
The important restriction on the function is that and . The reason is that either of those values would make the denominator zero. The domain of f(x) is these three intervals:
(-infinity, -7)
(-7, +7)
(+7, +infinity).
