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

domain

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

\frac{3}{2} \cdot 6

500 \times e^{- 0.25 \times 10}

5 x (3 x^{4})

5 x^{2} (2 x)
