domain of f(x)=e^{-x}+4

domain

f (x) = e^{- x} + 4

- \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{3 e ^{x}}{e ^{x} - 2}

f (x) = 2 sin (2 x)

f (x) = x^{2} - 20 x + 104

2 x^{2} - 13 x - 7

What is the domain of f(x)=e^{-x}+4 ?
The domain of f(x)=e^{-x}+4 is -infinity <x<infinity
