domain of f(x)=-2sqrt(x-3)-1

domain

f (x) = - 2 x - 3 - 1

x \geq 3

Interval Notation

[3, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 3

The function domain

x \geq 3

f (x) = 140 (1.6)^{x}

f (x) = (x + 5)^{\frac{2}{7}}

sin (6 x)

f (x) = \frac{x + 6}{x ( x + 11 )}

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

What is the domain of f(x)=-2sqrt(x-3)-1 ?
The domain of f(x)=-2sqrt(x-3)-1 is x>= 3
