domain

- 2.3

- \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) = ln (2 x + 1)

\frac{x + 9}{( x - 1 ) ( x - 7 )}

8 x

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

f (x) = - \frac{x}{x - 1}
