domain of arccos(2x)*ln(x^2)

domain

- \frac{1}{2} \leq x < 0 or 0 < x \leq \frac{1}{2}

Interval Notation

[- \frac{1}{2}, 0) \cup (0, \frac{1}{2}]

Solution steps

Find positive values for logs:

x < 0 or x > 0

Find known functions domain restrictions:

- \frac{1}{2} \leq x \leq \frac{1}{2}

Combine real regions and undefined points for final function domain

- \frac{1}{2} \leq x < 0 or 0 < x \leq \frac{1}{2}
