Table of values - Examples, Exercises and Solutions

A value table is the "preparatory work" that we are often asked to do before producing a graphical representation. Therefore, it is an inseparable part of the subject of graphs in general and the topic of functions in particular.

What is a Value Table?

A value table is actually a database, on which a discrete or continuous graph is based.
The data table lists the corresponding value of $Y$ for each $X$ .
The value table allows you to project and draw the graph conveniently and efficiently.
Below is an example of a value table for the function $Y=X+2$

Based on this value table, the following linear function can be plotted:
