Question

If there is a horizontal line, going through ( 0, 2), (1 , 2), ( 2, 2), (3 , 2) what is the domain and range?

Answer 1

range =2
domain = infinite

Explanation:

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!
