Question

What are the domain and range of f(x) = |x + 6|? Domain: (negative infinity, infinity); range: f(x) > 0 domain: x < -6; range: (negative infinity, infinity) domain: x > -6; range: (negative infinity, infinity) domain: (negative infinity, infinity) ; range: f(x) < 0

Answer 1

Answer:

Domain: $(-\infty,\infty)$

Range: $f(x) \ge 0$

Step-by-step explanation:

Given

$f(x) = |x + 6|$

Required

The domain and the range

First, we calculate the domain

$f(x) = |x + 6|$

The above function does not have roots or fraction, where x is the denominator. This means that the domain is all real numbers, i.e. $(-\infty,\infty)$

The range

The function is an absolute function; So, the minimum value is 0.

Hence, the range is:

$f(x) \ge 0$
