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

domain

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

- 1 < x \leq 1

Interval Notation

Solution steps

Find non-negative values for radicals:

- 1 < x \leq 1

Find undefined (singularity) points:

x = - 1

Combine real regions and undefined points for final function domain

- 1 < x \leq 1

y = 2^{x + 4}

\frac{( x + 5 )}{x ^{2} - 3 x}

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

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

\frac{2 x - 4}{2 - x}
