Summary: The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
â¢ If the graph opens upwards, the range will be greater than or equal to the y-coordinates of the vertex. â¢ If the graph opens downward, the range will be less than or equal to the y-coordinate of the vertex. Average rate of change: is constant on each straight line section (ray) of the graph.
