domain of f(x)=(2x-4)/(x^2+1)

domain

f (x) = \frac{2 x - 4}{x ^{2} + 1}

- \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^{3} - x + 1

\frac{\frac{x}{x + 1}}{\frac{1}{x}}

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

f (x) = cos (x) - 1

f (x) = lo g_{\frac{1}{2}} (x - 3)
