  1. Function Machine. Input: X = 8, Rule: Y equals, absolute value of X. Output: Y equals question mark.

    What is the absolute value of ?

  1. Function Machine. Input: X = question mark, Rule: Y equals, 3, minus the absolute value of X. Output: Y equals 2.

    Solve the equation by inspection.

  1. Function Machine. Input: K = negative 6, Rule: y equals, K divided by 2, plus 1. Output: y equals question mark.

    Substitute and evaluate.

  1. Function Machine. Input: X = 3, Rule: Y equals, negative X squared. Output: Y equals question mark.
