Q. Look at this set of ordered pairs:\newline(13,4)(13, 4)\newline(7,3)(7, 3)\newline(13,0)(13, 0)\newlineIs this relation a function?\newlineChoices:\newline(A) yes\newline(B) no
  1. Understand the problem: Step 11: Understand the problem.\newlineWe need to determine if the set of ordered pairs is a function. A relation is a function if each input (first number in each pair) maps to exactly one output (second number in each pair).
  2. Check unique outputs: Step 22: Check each input for unique outputs.\newlineFirst pair: (13,4)(13, 4)\newlineSecond pair: (7,3)(7, 3)\newlineThird pair: (13,0)(13, 0)\newlineHere, the input 1313 maps to two different outputs, 44 and 00.
  3. Determine function status: Step 33: Determine if the relation is a function.\newlineSince the input 1313 has more than one output, this relation is not a function.
