domain of f(x)= 1/(3+e^x)

domain

f (x) = \frac{1}{3 + 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) = t^{4} + t^{3} + t^{2} + 1

f (x) = \frac{6 x - 6}{x + 2}

\frac{1 - 7 x}{x}

f (x) = \frac{1}{x ^{2} + 3 x - 54}

1 - tan (π - x)
