domain of sqrt((12-x-x^2)/(|2x-5|))

domain

- 4 \leq x < \frac{5}{2} or \frac{5}{2} < x \leq 3

Interval Notation

[- 4, \frac{5}{2}) \cup (\frac{5}{2}, 3]

Solution steps

Find non-negative values for radicals:

- 4 \leq x < \frac{5}{2} or \frac{5}{2} < x \leq 3

Find undefined (singularity) points:

x = \frac{5}{2}

Combine real regions and undefined points for final function domain

- 4 \leq x < \frac{5}{2} or \frac{5}{2} < x \leq 3
