What function rule is represented in a given table?

• A. (• x 2) + 1 = ∆
• B. (• / 3) - 1 = ∆
• C. (• + 2) * 5 = ∆
• D. (• - 4) = ∆

Answer: (A)

To determine the function rule represented in a table, one approach is to analyze how the input values change in relation to the output values. The correct function rule suggests a pattern in the data that can be represented mathematically. The formula provided as the correct choice indicates a multiplication of the input by 2, followed by the addition of 1. This means for each input value, you first multiply it by 2, and then add 1 to get the corresponding output value. This process allows the analysis of the relationship between the two sets of values accurately. If you apply this rule to several values from the table, you will notice that when you take the input, multiply it by 2, and then add 1, you will arrive at the output, confirming that this function correctly describes the transformation from input to output as recorded in the table. This method of inspection should be applied to other potential answers in the table to see whether they align with the data presented. However, since the correct answer has been specified as option A, it’s essential to check that the manipulation outlined in this function aligns perfectly with all values represented in the table.
