    Question

    Examine the input-output table shown below.

    The rule of the input-output table is ___________

    1. Multiply by 2 and add 1    
    2. Multiply by 3 and add 2    
    3. Multiply by 3 and subtract 1    
    4. Multiply by 3 and subtract 2    

    hintHint:

    In the given question, we have to identify the function that the input-output table is carrying out. The inputs and outputs are given in the given question.

    The correct answer is: Multiply by 3 and subtract 2

      Step by step solution:
      First input : 3
      First output : 7
      here, 3 x 3 - 2 = 7
      similarly, in the second input : 4
      second output: 10
      here, 4 x 3 -1 = 10
      thus, the rule of the input-output table is  multiply by 3 and subtract 2
      Hence, option(a) is the correct option.
