domain of f(x)=-e^{1/5 x}

domain

f (x) = - e^{\frac{1}{5} 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) = \frac{x ^{2} + 4 x}{5 x ^{2} + 36 x + 64}

f (x) = x^{2} + 2 x + 6

f (x) = x^{2} + 2 x + 9

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

f (y) = - 3 y - 2
