In this activity, students will use graphs and lists to determine if sets of data represent functions or relations.
Students are given a data set and will create a scatter plot. After reading the definitions of relation and function, students are asked which term they think represents the voter data.
Students will apply the vertical line test to determine if the relation is a function. They will draw a vertical line on the plot and use the arrow keys to see where the line passes through more than one point.
