domain of f(x)=(x+2)^{1/2}

domain

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

x \geq - 2

Interval Notation

[- 2, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 2

The function domain

x \geq - 2

y = 8

f (x) = \frac{( x + 1 ) ^{2}}{x ^{2} - 3 x - 4}

y = - 2 x + 6

f (x) = 4 x^{3} + 4 x^{2} - 3 x - 1

What is the domain of f(x)=(x+2)^{1/2} ?
The domain of f(x)=(x+2)^{1/2} is x>=-2
