domain of f(x)= 4/5 x

domain

f (x) = \frac{4}{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

\frac{1}{3 - x}

\frac{x - 6}{x + 2}

f (x) = \frac{x ^{3}}{x ^{4} - 1}

f (x) = \frac{x ^{2} + 5 x + 6}{x + 3}

f (x) = 1 - e^{x}
