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

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

domain: x (less then or equal to) - 6; range: (negative infinite, infinite)

domain: x (greater than or equal to) - 6; range: (negative infinite, infinite)

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

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.
