domain of (1/(sqrt(x)))^2-4(1/(sqrt(x)))

domain

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

y = - 7 x + 42, (7, - 8)

\frac{4 x - 3}{- 4 x + 2}

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

f (x) = x^{5} - 9 x^{3} + 9 x

f (x) = \frac{1}{8 x - 16}
