domain of f(x)= 5/(sqrt(x-3))

domain

f (x) = \frac{5}{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) = 35 - 7 x

5 sin (2 x + π)

y = \frac{2 x ^{2} - 3 x + 1}{3 x ^{4} + 4 x ^{2} + 2}

3 x - 9

x^{3} - 3 x
