Question

Graph the function y = √ x + 4 – 2. Then state the domain and range of the function.

Answer 1

Here!! I hope this helps you !!

Answer 2

Domain : [-4, ∞)

Range : [ -2, ∞)

Explanation:

The given function is y =
`√((x+4))-2`

Domain of the given function will be

(x + 4) ≥ 0

[ Since square root of numbers less than 0 is not possible ]

Domain : x ≥ (-4)

Or [-4, ∞) will be the domain

Now range of the function will be x ≥ -2

[ -2, ∞) will be the range of the given function.
