domain of f(x)=-sqrt(x-4)+9

domain

f (x) = - x - 4 + 9

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{4 x - 3}{x}

f (x) = \frac{- 7}{6} x

f (x) = arcsin (ln (\frac{x}{3}))

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

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

What is the domain of f(x)=-sqrt(x-4)+9 ?
The domain of f(x)=-sqrt(x-4)+9 is x>= 4
