The graph of an absolute value function opens up and has a vertex of (0, - 3).

The domain of the function is =

A. ( - ∞,-3]

B.[-3, ∞)

C. ( - ∞, ∞)

The range of the function is =

A. ( - ∞,-3]

B.[-3, ∞)

C. ( - ∞, ∞)

Absolute value function domain is all real numbers

absolute value has vertex of (0,-3)

and it opens up

means that the lowest y value is - 3

highest is infinity

domain=-inifnity to infinity

range=-3 to positive initnify

the answer is C for the domain and B for the range
