The problem describes two sets:

- Set \( A = \{2, 4, 6, 8, 10\} \)
- Set \( B = \{1, 2, 3, 4, 5, 6, 7\} \)

The function \( f(x) \) is defined as a "two-times relation," meaning \( f(x) = \frac{x}{2} \), mapping elements of set \( A \) to set \( B \). You are asked to present the function in the following forms:

1. **Himpunan pasangan berurutan (Ordered pairs)**:
   We will list the pairs \((x, f(x))\), where \( x \in A \) and \( f(x) \in B \).

2. **Diagram panah (Arrow diagram)**:
   We'll represent the relation using arrows, mapping each element from set \( A \) to its corresponding value in set \( B \).

Let's first define the ordered pairs for the function \( f(x) = \frac{x}{2} \):

- \( f(2) = \frac{2}{2} = 1 \)
- \( f(4) = \frac{4}{2} = 2 \)
- \( f(6) = \frac{6}{2} = 3 \)
- \( f(8) = \frac{8}{2} = 4 \)
- \( f(10) = \frac{10}{2} = 5 \)

### 1. Ordered pairs:

\[
\{(2, 1), (4, 2), (6, 3), (8, 4), (10, 5)\}
\]

### 2. Arrow diagram:
In this diagram, we will show arrows from each element in set \( A \) pointing to the corresponding element in set \( B \) according to the function \( f(x) \).

- \( 2 \rightarrow 1 \)
- \( 4 \rightarrow 2 \)
- \( 6 \rightarrow 3 \)
- \( 8 \rightarrow 4 \)
- \( 10 \rightarrow 5 \)

Would you like a more detailed explanation or a visual diagram of the arrow representation? 

Here are five related questions you might find helpful:

1. What is the domain and codomain of the function \( f(x) \)?
2. How do we verify if the function is one-to-one (injective)?
3. Is \( f(x) \) onto (surjective) given sets \( A \) and \( B \)?
4. How would the function change if set \( B \) had different values?
5. Can we define the inverse function \( f^{-1}(x) \), and what would it look like?

**Tip**: When defining a function, it's crucial to ensure that every element of the domain maps to exactly one element in the codomain.

Diketahui himpunan A = {2, 4, 6, 8, 10} dan himpunan B = {1, 2, 3, 4, 5, 6, 7}. Fungsi f(x) merupakan relasi dua kali dari himpunan A ke himpunan B. Sajikan fungsi f(x) dalam bentuk: 1) himpunan pasangan berurutan, 2) diagram panah, dan
