domain of f(x)= 1/(sqrt(5x-15))

domain

f (x) = \frac{1}{5 x - 15}

x > 3

Interval Notation

(3, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 3

Find undefined (singularity) points:

x = 3

Combine real regions and undefined points for final function domain

x > 3

f (x) = 2 (x - 1)^{2} - 3

- \frac{x ^{2} + 4 x - 12}{32}

f (x) = 2 - ∣ x ∣

\frac{1}{- 3 x + 1}

f (x) = x - (y - 1)^{2} = 0
