domain of f(x)=(sqrt(4x-8))/(sqrt(x+3))

domain

f (x) = \frac{4 x - 8}{x + 3}

x \geq 2

Interval Notation

[2, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 2

Find undefined (singularity) points:

x = - 3

Combine real regions and undefined points for final function domain

x \geq 2

f (x) = \frac{4 x + 2}{1 - 6 x}

\frac{18}{x} - 1

y = x^{2} + 1

f (x) = tan (x) sin (6 x^{3})

\frac{1}{4}
