Q. Look at this set of ordered pairs:\newline(2,3)(2, 3)\newline(5,18)(5, 18)\newline(9,16)(9, 16)\newline(15,12)(15, 12)\newlineIs this relation a function?\newlineChoices:\newline(A) yes\newline(B) no
  1. Understand function definition: Step 11: Understand the definition of a function. A relation is a function if each input (xx-value) has exactly one output (yy-value).
  2. Check for duplicates: Step 22: Check the xx-values in the ordered pairs for duplicates. The pairs are (2,3)(2, 3), (5,18)(5, 18), (9,16)(9, 16), and (15,12)(15, 12).
  3. List xx-values: Step 33: List the xx-values: 2,5,9,152, 5, 9, 15. Since there are no repeated xx-values, each xx-value is paired with exactly one yy-value.
