domain of sqrt((1-x)/(x+2))

domain

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

- 2 < x \leq 1

Interval Notation

Solution steps

Find non-negative values for radicals:

- 2 < x \leq 1

Find undefined (singularity) points:

x = - 2

Combine real regions and undefined points for final function domain

- 2 < x \leq 1

lo g_{10} (2 x - 12)

y = \frac{1 + x}{x ^{2} - 4}

f (x) = 4 (x + 1) 2 + x - 3 x + 1 - 49

f (x) = - x + 3 + 3

f (x) = \frac{3 x ^{2} + 1}{x ^{2} - 1}
