Question

Does the domain of the function f(x) = alt="\sqrt{1+x}" align="absmiddle" class="latex-formula"> include x = -2?

Answer 1

The value x = - 2 is not part of the domain of the function f(x) = √(x + 1).

Is a given point part of the domain of a radical function?

Radical functions are functions that involves root operators. We see here a radical function of the form f(x) = √(x + a), whose domain is x ∈ [- a, + ∞), that is, x ≥ - a. If we know that f(x) = √(x + 1), then a = 1 and the domain of the function is x ∈ [- 1, + ∞), that is, x ≥ - 1.

Hence, the value x = - 2 is not part of the domain of the function f(x) = √(x + 1).
