domain of f(x)=(1000)/(100+900e^{-x)}

domain

f (x) = \frac{1000}{100 + 900 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) = 2 - x^{2}

(1, 5), (- 3, - 5)

f (x) = \frac{8 x ^{3} + 7 x ^{2}}{9 x ^{3} - 2}

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