domain of (1/(sqrt(x)))^2-8(1/(sqrt(x)))

domain

(\frac{1}{x})^{2} - 8 (\frac{1}{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) = cos (\frac{1}{2} x)

4 x - 16

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

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

(\frac{1}{3})^{x}
