Question

How do you graph the equation `y=-4` by making a table and what is its domain and range?

Answer 1

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`.
