To determine whether the relation $$ \{(4,3),(5,4),(9,9)\} $$ is a function, we need to check if each input (or first element of each ordered pair) is associated with exactly one output (or second element of each ordered pair).

1. **Check for uniqueness of inputs:**
   - The inputs (first elements) are $$ 4, 5, $$ and $$ 9 $$.
   - Each input is unique and does not repeat.

Since each input corresponds to exactly one output, the relation is indeed a function.

2. **Identify the domain:**
   - The domain consists of all the first elements of the ordered pairs.
   - Therefore, the domain is $$ \{4, 5, 9\} $$.

3. **Identify the range:**
   - The range consists of all the second elements of the ordered pairs.
   - Therefore, the range is $$ \{3, 4, 9\} $$.

In conclusion:
- Yes, this is a function.
- The domain is $$ \{4, 5, 9\} $$.
- The range is $$ \{3, 4, 9\} $$.
This is a function. The domain is {4, 5, 9} and the range is {3, 4, 9}.

Determine whether the relation is a function. Give the domain and the range for the relation. \( \{(4,3),(5,4),(9,9)\} \) Is this a function? No The domain is \( \{4,5,9\} \). (Use a comma to separate answers as needed.) The range is \( \{3,4,9\} \). (Use a comma to separate answers as needed.)
