Consider the following three tables with input and output variables. Decide which table(s) represent a function.

To determine whether a set of input and output variables in tables represent a function, we need to check if each input corresponds to exactly one output. If an input value maps to more than one output value, then it does not represent a function.

Steps to Determine If the Tables Represent a Function

1. Examine Each Table:

   • Look at the pairs of input and output values in each table.

2. Identify Unique Inputs:

   • Create a list of the input values for each table.

3. Check Output Consistency:

   • For each unique input, check if it corresponds to one and only one output value.

4. Decision:

   • If every input in the table leads to one output, that table represents a function. If any input has multiple outputs, that table does not represent a function.

Summary of Findings

• Table 1: [Evaluate outputs for duplicate inputs]
• Table 2: [Evaluate outputs for duplicate inputs]
• Table 3: [Evaluate outputs for duplicate inputs]

Final Answer

• Summarize which tables represent a function based on the evaluations above.
