domain of f(x)=sqrt(|x|)

domain

f (x) = ∣ x ∣

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

Find non-negative values for radicals:

- \infty < x < \infty

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

\frac{6 x}{x + 7}

arctan (\frac{x - 1}{x + 1})

f (x) = 3 x^{2} ln (\frac{x}{4})

f (x) = 2^{x} - 6

f (x) = \frac{- 8 - 9 x}{8 x - 7}
