domain of sqrt(x+4)-(sqrt(7-x))/x

domain

x + 4 - \frac{7 - x}{x}

- 4 \leq x < 0 or 0 < x \leq 7

Interval Notation

[- 4, 0) \cup (0, 7]

Solution steps

Find non-negative values for radicals:

- 4 \leq x \leq 7

Find undefined (singularity) points:

x = 0

Combine real regions and undefined points for final function domain

- 4 \leq x < 0 or 0 < x \leq 7
