domain of f(x)=5e^{-x}

domain

f (x) = 5 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 - 3) (x^{2} + 8 x + 16)

t^{2} - 4

g (x) = ln (x - x^{3})

f (x) = 5 x^{2} - ∣ 5 x ∣

t^{2} - 5
