domain of f(x)=(8x)/(sqrt(x-5))

domain

f (x) = \frac{8 x}{x - 5}

x > 5

Interval Notation

(5, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 5

Find undefined (singularity) points:

x = 5

Combine real regions and undefined points for final function domain

x > 5

\frac{3 t - 9}{3 t ^{2} - 12}

arccos (2 x)

f (x) = 3 x^{4} - 7

f (x) = 6 x^{2} - 6

f (x) = \frac{x ^{2} - 3}{5 x ^{2} + 2 x + 1}

What is the domain of f(x)=(8x)/(sqrt(x-5)) ?
The domain of f(x)=(8x)/(sqrt(x-5)) is x>5
