Explanation:

There are two inverse linear functions graphed. One of the is decreasing up to x = 3 excluded, the other one is increasing from the point x = 3 included.

Domain range of the decreasing one is:

• ( - oo, 3 )

Domain range of the increasing one is:

• [ 3, +oo )

Correct choices are: A, B and D

Note: A and B are same
