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

domain

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

- \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

f (x) = x + 7

f (x) = \frac{x + 1}{x - 2}

y = 6 x^{2} - 4

y = \frac{- 1}{x}

x^{\frac{3}{5}}
