Given a table showing points on the graph of a function, determine whether or not the rate of change is uniform.
To determine whether the rate of change is uniform for the function given by the table, follow these steps:
Let's calculate the rate of change between these points:
1. Between  and :
   The rate of change is:
   
2. Between  and :
   The rate of change is:
   
3. Between  and :
   The rate of change is:
   
All calculated rates of change are equal to , indicating the rate of change is uniform between each consecutive pair of points.
Therefore, the rate of change is Uniform.
Uniform
Given the following graph, determine whether function is constant
A uniform rate of change means the function increases (or decreases) by the same amount for every equal step in x. It's what makes a line straight!
Even if the first two pairs have the same rate, the third pair might be different! You need to check every single pair to be sure the rate is truly uniform throughout.
Then the rate of change is non-uniform! This means the function is not linear - it could be quadratic, exponential, or some other type of curve.
No! You must use consecutive pairs only. Using random points might give you an average rate that hides non-uniform sections in between.
Congratulations! When all consecutive rates equal the same value (like ), your function is linear with a uniform rate of change.
