domain of (x+1)/(|x|+1)

domain

\frac{x + 1}{∣ x ∣ + 1}

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

Find undefined (singularity) points:

No real undefined points

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

- \infty < x < \infty

9 x + 20

\frac{6}{x ^{2} + 4}

f (x) = π - 2

4 y = x^{3}

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