Answer:
Option C is NOT a function.
Step-by-step explanation:
For these functions we will use<em> subtraction</em> as our example. With option A the pattern is: <em> -8, -7, -6, -5</em>. Therefore option A <em>is a function</em>. With option C the pattern is: <em>3, 3, 3, 2</em>. Therefore this is <em>not </em>a function. With option B the pattern is <em>0, 0, 0, 0</em>. Therefore this<em> is a function</em>. With option D the pattern is: <em>-6, -2, 2, 6</em>. Therefore this<em> is a function. </em>
