domain of-2/(sqrt(x))

domain

- \frac{2}{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) = x^{2} - 2 x

(1.9) 7

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

f (x) = 3 - \frac{5}{x ^{4}}

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