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

domain

f (x) = - 3 + 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) = \frac{x ^{2} + 5}{x ^{2} + 81}

g (x) = - 3 x + 12

5 x + 25

f (x) = \frac{1}{4 x + 7}

What is the domain of f(x)=-3+sqrt(x-4) ?
