Explanation:

Step1: Find domain for relation 2

Domain is set of input values.
$$\{5,7,9\}$$

Step2: Find range for relation 2

Range is set of output values.
$$\{4,8,10\}$$

Step3: Check if relation 2 is a function

Each input has exactly one output.

Step4: Find domain for relation 3

Domain is set of first - elements of ordered pairs.
$$\{4,5\}$$

Step5: Find range for relation 3

Range is set of second - elements of ordered pairs.
$$\{2,3,5,6\}$$

Step6: Check if relation 3 is a function

Input \(5\) has two outputs (\(5\) and \(6\)).

Answer:

For relation 2:

• Domain: \(\{5,7,9\}\)
• Range: \(\{4,8,10\}\)
• Function: YES

For relation 3:

• Domain: \(\{4,5\}\)
• Range: \(\{2,3,5,6\}\)
• Function: NO
