The rate of change of a function represented by a table of values allows us to compare the variation of the values of (the independent variable of the function) with the variation of the values of (dependent variable of the function). This comparison enables us to determine if the intervals are fixed or not, and, consequently, if the rate of change is constant or not.
Given the following graph, determine whether function is constant
For each we will fill in the corresponding .
We will see at what rate the variables increase in the table.
If the variables grow at the same rate, we can determine that the rate of change of the function is constant.
We will illustrate this topic with the help of two different tables
Representation of the function in table
In this table, the first column represents the variables and the second, the variables according to their correspondence.
If we look closely, we will see that there is a fixed rate that is maintained throughout all the values. For every increase in there is a corresponding increase of in the variables.
Given the following graph, determine whether the rate of change is uniform or not
Given the following graph, determine whether the rate of change is uniform or not
Given the following graph, determine whether the rate of change is uniform or not
Table representation of a function with a non-constant rate of change
Also in this table, the first column represents the variables and the second the variables according to their correspondence.
If we look closely, we will see that in this case there is no fixed rate that remains stable across all values.

Given the following graph, determine whether the rate of change is uniform or not
Let's remember that if the function is not a straight line, its rate of change is not uniform.
Since the graph is not a straight line - the rate of change is not uniform.
Non-uniform
Given the following graph, determine whether the rate of change is uniform or not
Let's remember that if the function is not a straight line, its rate of change is not uniform.
Since the graph is not a straight line - the rate of change is not uniform.
Non-uniform
Given the following graph, determine whether the rate of change is uniform or not
Remember that if the function is a straight line, its rate of change will be constant.
Since the graph is a straight line - the rate of change is constant.
Uniform
Look at the graph below and determine whether the function's rate of change is constant or not:
First we need to remember that if the function is not a straight line, its rate of change is not constant.
The rate of change is not uniform since the function is not a straight line.
Not constant
