domain of f(x)=(2x)/(sqrt(x-3))

domain

f (x) = \frac{2 x}{x - 3}

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) = - x^{2} - 9 x - 20

y = lo g_{10} (x)

f (x) = ln (9 - x^{2})

f (x) = x + 4

y = x^{2} + 4 x - 2
