domain of f(x)=|x+2|

domain

f (x) = ∣ x + 2 ∣

- \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) = - x^{2} + 2 x

(- 4.6) (3.7)

f (x) = 4 - x

- \frac{1}{x}

(- 2.11) \frac{- 4}{3}
