domain of f(x)= 1/(sqrt(x-15))

domain

f (x) = \frac{1}{x - 15}

x > 15

Interval Notation

(15, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 15

Find undefined (singularity) points:

x = 15

Combine real regions and undefined points for final function domain

x > 15

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

y = - 6

f (x) = - 3 x + 1

3 x

\frac{1 - x}{1 + x}
