domain of f(x)=2sqrt(x+3)-4

domain

f (x) = 2 x + 3 - 4

x \geq - 3

Interval Notation

[- 3, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 3

The function domain

x \geq - 3

\frac{2}{( x - 5 ) ( x + 5 )}

f (x) = 1 + \frac{1}{x} - \frac{2}{x ^{3}}

f (x) = \frac{x ^{2} - 5 x - 36}{3 x}

- \frac{x - 1}{4}

f (x) = x + 3 y = - 2

What is the domain of f(x)=2sqrt(x+3)-4 ?
The domain of f(x)=2sqrt(x+3)-4 is x>=-3
