domain of f(x)= 2/(9+e^x)

domain

f (x) = \frac{2}{9 + e ^{x}}

- \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{1}{2 - 10 x + 25}

5^{x + 3} - 1

14400 + 600 x + x^{2}

\frac{x ^{3} + 2 x ^{2} + x}{x ^{2} + x - 6}

f (x) = (x - 2) 2 - 4
