domain of 3x-1

domain

3 x - 1

- \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{2}{x - 3} - 2

f (x) = x^{2} + 4 x + 4

3 - x + x^{2} - 4

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

g (x) = \frac{- x - 2}{x + 4}
