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

domain

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

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

f (x) = lo g_{5} (x)

f (x) = \frac{x ^{2} + 5 x + 6}{x + 4}

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

x^{4} - 4 x^{2}
