Question

What is the domain and range of f(x) = |x + 6|?

Answer 1

Answer:

domain: (negative infinite,infinite); range: f(x) (greater than or equal to $0$

Step-by-step explanation:

we have

$f\left(x\right)=\left|x+6\right|$

The vertex of the function is the point $(-6,0)$

The domain is the interval--------> (-∞,∞)

The domain is all real numbers

The range is the interval ------> [0,∞)

$f(x)\geq 0$

The range is all real numbers greater than or equal to zero

To better understand the problem see the attached figure

Answer 2

X can be any real value so domain is (-INF, INF) .  The range can be 0 or greater than zero because it is an absolute function.

The first choice is the correct one.
