An interval graph in graphical theory is indeed an undirected graph formed by an interval set just on true line, with a top for every interval as well as an edge between vertex v to intersections. Graph intervals and these graphs are chordal graphs and graphs that are perfect, and the further discussion can be defined as follows:
Given:

![\bold{Interval \ \[-6, 3\]}](https://tex.z-dn.net/?f=%5Cbold%7BInterval%20%5C%20%5C%5B-6%2C%203%5C%5D%7D)
To find:
Domain=?
Solution:
The
is a graphic over the
interval.
A<em><u> graph of the domain</u></em>
is indicated mostly by the <em><u>transformation </u></em>that <em><u>horizontal shifts</u></em> to combat
.
