Question

How would I begin this?

Proceed as in Example 1. Translate the words into an appropriate function.

A wire of length \( L \) is cut \( x \) units from its left end. As shown in the figure below, the piece of wire of length \( x \) (blue in the figure) is bent into the shape of a circle, whereas the remaining piece of wire of length \( L - x \) (red in the figure) is bent into the shape of a square. Express the sum of the areas, \( A \), as a function of \( x \).

\[ A(x) = \]

Give the domain of the function. (Enter your answer using interval notation.)

---

**Diagrams Explanation:**

- **(a) Wire of length \( L \):** This is a straight horizontal line indicating the total length \( L \).

- **(b) Wire cut \( x \) units from left end:**
  - **Circle:** The section in blue, representing the length \( x \), is formed into a circle.
  - **Square:** The section in red, representing the length \( L - x \), is formed into a square.

The diagram illustrates the division of the wire into two parts, one forming a circle and the other a square, based on the variable \( x \).
