domain of (2x)/(x^2+2)

domain

\frac{2 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) = \frac{x - 4}{25 - x ^{2}}

\frac{3 x + 8}{x - 2}

\frac{3 x + 2}{2 x - 5}

f (x) = x y^{2} - x + 3 y^{2} + 1 = 0

f (x) = - 5 x + 9
