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

domain

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

x > - 3

Interval Notation

(- 3, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 3

Find undefined (singularity) points:

x = - 3

Combine real regions and undefined points for final function domain

x > - 3

f (x) = \frac{x ^{2} - 4}{x - 1}

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

e^{- x^{2}}

f (x) = \frac{x}{x}

\frac{1 - x ^{2}}{x ^{3} + x}
