domain of f(x)= 7/(sqrt(x-8))

domain

f (x) = \frac{7}{x - 8}

x > 8

Interval Notation

(8, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 8

Find undefined (singularity) points:

x = 8

Combine real regions and undefined points for final function domain

x > 8

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

f (x) = 0 - 1

f (x) = \frac{3}{( x - 8 ^{2} + 14 x )}

f (x) = 9 x^{3} + 3 x^{2} = 3 x

y = \frac{2 - 2 x}{x - 2}

What is the domain of f(x)= 7/(sqrt(x-8)) ?
The domain of f(x)= 7/(sqrt(x-8)) is x>8
