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

domain

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

- \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 (r) = 2 π r^{2} + 8 π r

\frac{3}{t - 6}

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

f (x) = e^{- 11 x}

4 - x, x < 1, 8 x - 5, x \geq 1
