domain of f(x)=(sqrt(3-x))/(sqrt(x+1))

domain

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

- 1 < x \leq 3

Interval Notation

(- 1, 3]

Solution steps

Find non-negative values for radicals:

- 1 \leq x \leq 3

Find undefined (singularity) points:

x = - 1

Combine real regions and undefined points for final function domain

- 1 < x \leq 3

- x + 3

\frac{- 4 - 3 x}{7 x - 5}

\frac{5 x + 2}{x - 3}

3 e^{x - 2} + 1
