domain of f(x)=(-3x)/(x^2+4)

domain

f (x) = \frac{- 3 x}{x ^{2} + 4}

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

\frac{2 x - 6}{x + 6}

9 - x

f (x) = \frac{9 x ^{3} - 5 x ^{2} - 5 x}{6 - 4 x - 10 x ^{3}}

(2 x + 1)^{2} - 1
