domain of f(x)=x^2-9x-5

domain

f (x) = x^{2} - 9 x - 5

- \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{x - 5}{x - 2}

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

f (x) = x + 13

f (x) = \frac{1}{2} x - \frac{7}{2}

\frac{2}{x + 4}
