domain of f(x)=-sqrt(x-1)-3

domain

f (x) = - x - 1 - 3

x \geq 1

Interval Notation

[1, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 1

The function domain

x \geq 1

(2, 3), (12, - 15)

f (x) = \frac{4}{x ^{2} + 8}

f (x) = \frac{2}{7 - x}

f (x) = - 2^{x} + 100

f (x) = \frac{x + 6}{x ^{2} - 25}

What is the domain of f(x)=-sqrt(x-1)-3 ?
The domain of f(x)=-sqrt(x-1)-3 is x>= 1
