domain of f(x)= 2/(sqrt(1+x))

domain

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

x > - 1

Interval Notation

(- 1, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 1

Find undefined (singularity) points:

x = - 1

Combine real regions and undefined points for final function domain

x > - 1

f (x) = - x^{2} + 16

3^{x + 3}

f (x) = \frac{( 2 x - 6 )}{5}

\frac{8}{49 x} - 5

\frac{lo g _{10} ( x - 2 )}{18 - 2 x}
