Q. Look at this set of ordered pairs:\newline(18,15)(18, 15)\newline(11,8)(11, 8)\newline(4,19)(4, 19)\newline(8,16)(8, 16)\newlineIs this relation a function?\newlineChoices:\newline(A) yes\newline(B) no
  1. Understand Function Definition: Step 11: Understand the definition of a function.\newlineA relation is a function if each input (first number in each ordered pair) has exactly one output (second number in each ordered pair). We need to check if any input value repeats with different outputs.
  2. List Input Values: Step 22: List all the input values from the ordered pairs.\newlineInputs are 1818, 1111, 44, and 88.
  3. Check Repeated Inputs: Step 33: Check for repeated input values.\newlineOnly the input value 88 appears more than once.
  4. Check Outputs for Repeated Input: Step 44: Check the outputs for the repeated input.\newlineFor the input 88, the outputs are 1616. Since there is no other pair with the input 88 having a different output, there is no contradiction to the definition of a function.
