domain of f(x)=|x^2-9|

domain

f (x) = x^{2} - 9

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

f (x) = \frac{( ∣ x + 5 ∣ - 2 )}{x - 3}

x + 4 - x - 9

f (x) = 5 + x

f (x) = \frac{- 2}{x ^{2} + 2 x - 35}

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

What is the domain of f(x)=|x^2-9| ?
The domain of f(x)=|x^2-9| is -infinity <x<infinity
