domain of e^{-x^2}

domain

e^{- x^{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}{x}

\frac{1 - x ^{2}}{x ^{3} + x}

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

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

f (x) = x e^{- x^{2}}
