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

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: $- \infty , + \infty$. (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: $- \infty , + \infty$. (Negative and Postive Infinity).
Ranger: $y = - 4$.
