domain of (250)/(1+e^{-2x)}

domain

\frac{250}{1 + e ^{- 2 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) = (x^{2} + 2)^{2} + 1

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

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

\frac{x ^{2} + 4 x - 21}{x - 2}

f (x) = \frac{2 x + 4}{x - 3}
