domain of f(x)=(x-9)^{1/2}

domain

f (x) = (x - 9)^{\frac{1}{2}}

x \geq 9

Interval Notation

[9, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 9

The function domain

x \geq 9

f (x) = 4 x^{2} + x + 4

\frac{1}{x - 2} + 1

f (x) = \frac{6}{8 - x}

f (x) = 2 x^{2} + 8 x - 10

y = 3 x - 9

What is the domain of f(x)=(x-9)^{1/2} ?
The domain of f(x)=(x-9)^{1/2} is x>= 9
