domain of f(x)=(sqrt(x-4))/(x^2+x-20)

domain

f (x) = \frac{x - 4}{x ^{2} + x - 20}

x > 4

Interval Notation

(4, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 4

Find undefined (singularity) points:

x = 4, x = - 5

Combine real regions and undefined points for final function domain

x > 4
