See Below for Explanation:

Explanation:

Since we are given the equation #y=-4#, we have all the information we need to graph it (in short we do not need to make a table really).

Since this equation is #y=-4#, this will create a horizontal line at #-4# on the graph. See below:

As for the domain and range.

Domain: #-oo,+oo#. (Negative and Postive Infinity).

This is because the horizontal line at #y=-4# will go on forever since we weren't given a restricted domain.

Ranger: #y=-4#.

This is due to the fact that whether or not we have a restricted domain, we will never move up or down the y-axis.

Note: If you want to see a table of this on your calculator, simply input #y=-4#.

Domain: #-oo,+oo#. (Negative and Postive Infinity).

Ranger: #y=-4#.
