domain of 1/2 x-4

domain

\frac{1}{2} x - 4

- \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{8 x ^{3} + 12 x ^{2} + 2 x + 6}{2 x ^{2} + 3}

\frac{lo g _{3} ( x )}{x + 1}

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

f (x) = \frac{x}{x - 3}

f (x) = \frac{x - 3}{x ^{2} + 3 x - 40}
