Question

determine if the following is a function, and if it is a one - to - one function.\\{(0,6),(8,9),(6,5),(5,3),(6,7)\\}
answer
\\(\bigcirc\\) not a function
\\(\bigcirc\\) a function, not one - to - one
\\(\bigcirc\\) a one - to - one function

Explanation:

Step1: Check if it's a function

A function requires that each input (first element of the ordered pair) has exactly one output (second element). Here, the input \( 6 \) appears in \((6,5)\) and \((6,7)\), so the same input has different outputs. Thus, it's not a function.

Answer:

Not a function
