domain of f(x)=|x-8|

domain

f (x) = ∣ x - 8 ∣

- \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 + 1}{x - 1}

f (x) = \frac{5 x + 2}{12} + x

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

x^{2} - 5 x + 4

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