Look at this set of ordered pairs: (19, 18) (13, 13) (17, 12) (14, 0) 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. Check for Duplicates: Step 2: List all the first numbers of the ordered pairs to check for duplicates: - First numbers: 19, 13, 17, 14 - Check for duplicates: No duplicates found. Confirm Function Status: Step 3: Since there are no repeating first numbers, each input has only one output. This means the relation is a function.

(A) yes

\newline

(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.
Check for Duplicates: Step $2$ : List all the first numbers of the ordered pairs to check for duplicates: $\newline$ - First numbers: $19$ , $13$ , $17$ , $14$ $\newline$ - Check for duplicates: No duplicates found.
Confirm Function Status: Step $3$ : Since there are no repeating first numbers, each input has only one output. This means the relation is a function.
