domain of f(x)=(x+3)/8

domain

f (x) = \frac{x + 3}{8}

- \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 ( x - 1 )}{x + 5}

3 x - 5 - 2 x + 1

\frac{6 x}{5 x - 15}

f (x) = \frac{x}{x ^{2} - 144}

\frac{1}{3 \cdot x ^{2} + 2}
