Example Questions
Example Question #1 : Understand Functions: Ccss.Math.Content.8.F.A.1
Select the table that properly represents a function.
Each of the tables provided contains sets of ordered pairs. The input column represents the x-variables, and the output column represents the y-variables. We can tell if a set of ordered pairs represents a function when we match x-values to y-values.
In order for a table to represents a function, there must be one and only one input for every output. This means that our correct answer will have all unique input values:
Functions cannot have more than one input value that is the same; thus, the following tables do not represent a function:
