domain of g(x)=sqrt(x-4)

domain

g (x) = x - 4

x \geq 4

Interval Notation

[4, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 4

The function domain

x \geq 4

f (x) = (x - 8)^{2}

f (x) = 1 - ln (3 x)

f (x) = \frac{1}{4.7 x - 5.3 x ^{2}}

f (x) = \frac{ln ( x + 3 )}{x ^{2} - 16}

f (x) = \frac{3}{x ^{2} - 8 x + 15}
