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

domain

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

f (x) = \frac{x ^{2} + 17 x + 72}{x ^{2} + 2 x - 80}

\frac{6 x}{x - 4}

4 - \frac{1}{( x + 1 ) ^{2}}

\frac{6 x}{x - 3}

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