domain of f(x)=e^{-3x}

domain

f (x) = e^{- 3 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) = 1 + x

f (x) = \frac{1}{5 + e ^{2 x}}

3 x^{4} - 15

f (x) = \frac{13 x ^{2}}{7 x ^{2} + 6}

y = \frac{1}{2} x + 2
