domain of 3/(sqrt(x))

domain

\frac{3}{x}

x > 0

Interval Notation

(0, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 0

Find undefined (singularity) points:

x = 0

Combine real regions and undefined points for final function domain

x > 0

f (x) = 6 + 6 x

f (x) = \frac{1}{5 x + 6}

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

2 x - y = - 4

f (x) = \frac{x ^{3} - x}{x ^{2} - 4}
