Look at this set of ordered pairs: (13, 6) (15, 5) (8, 1) (9, 4) Is this relation a function? Choices: (A)yes (B)no

Understand Function Definition: Step 1: Understand what a function is in terms of ordered pairs. A relation is a function if each input (first number in the pair) has exactly one output (second number in the pair). We need to check if any first number repeats with a different second number. List First Numbers: Step 2: List all the first numbers of the ordered pairs to check for repeats: 13, 15, 8, 9. None of these numbers are repeated, which means each input has only one output. Check for Repeats: Step 3: Since no input value is repeated with a different output value, this relation is a function.

(B) no

Understand Function Definition: Step $1$ : Understand what a function is in terms of ordered pairs. A relation is a function if each input (first number in the pair) has exactly one output (second number in the pair). We need to check if any first number repeats with a different second number.
List First Numbers: Step $2$ : List all the first numbers of the ordered pairs to check for repeats: $13, 15, 8, 9$ . None of these numbers are repeated, which means each input has only one output.
Check for Repeats: Step $3$ : Since no input value is repeated with a different output value, this relation is a function.
