domain of f(x)=sqrt(x-13)

domain

f (x) = x - 13

x \geq 13

Interval Notation

[13, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 13

The function domain

x \geq 13

f (x) = \frac{∣ x - 3 ∣}{x - 3}

f (x) = \frac{1}{5} x - 4

f (x) = 3 x^{3} - 36 x

f (x) = \frac{3 x - 1}{3 x + 9}
