range =2
domain = infinite


Because its a horizontal line, it goes on forever and therefore, has an infinite domain. Note that the domain is all the possible values x can have. In this case, x can take on any value because it stays the same throughout.

The range does not change because it is a line that stays in the same position on the y-axis throughout. Remember that the range is all the possible values y can have. Here, y can only have the value of 2.

Hope this helps!
