Question

What is the domain and range of `y = | x + 3|`?

Answer 1

Domain : `x in RR or (-oo , oo)`
Range: `y >=0 or [0 , oo)`

Explanation:

`y = abs(x+3)` . Domain : Input of `x` is any real number.

Domain `x in RR or (-oo , oo)`

Range : Output `y >=0 or [0 , oo)`

graph{abs(x+3) [-10, 10, -5, 5]} [Ans]
