domain of f(x)=|x+1|

domain

f (x) = ∣ x + 1 ∣

- \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} + x - 9

f (x) = 2^{x}

x^{2} - 4 x - 12

f (x) = x^{2} - 5 x - 14

f (x) = t + 2

What is the domain of f(x)=|x+1| ?
The domain of f(x)=|x+1| is -infinity <x<infinity
