domain of f(x)=|x-7|-9

domain

f (x) = ∣ x - 7 ∣ - 9

- \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{\frac{x}{x - 4}}{\frac{7}{x + 9}}

\frac{1}{x ^{2} - 5 x}

- 3 y - 1

f (x) = x^{3} - 11 x^{2}

f (x) = \frac{2 x - 1}{x ^{2} - 4}
