domain of x/(x^2+4)

domain

\frac{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

in v erse (x - 1)^{3} + 2

a sy m pt o t es \frac{x ^{3} + x ^{2} - 6 x}{4 x ^{2} + 4 x - 8}

d o main f (x) = \frac{x - 4}{x ^{2} - 2 x - 8}

in t erce pt s x^{4} + 62 x^{2} + 128 x + 65

in v erse f (x) = e^{\frac{2 x}{2 x ^{2} - 1}}
