Find the domain of the function
\[ h(x) = \frac{x^4 - 4x^2 + 3}{|x - 5| + |x + 2|}. \] |
The domain of a function is the set of all possible values of $x$ for which the function is defined.
We are given the function $h(x) = \frac{x^4 - 4x^2 + 3}{|x - 5| + |x + 2|}$.
The function is a rational function, where the numerator is $f(x) = x^4 - 4x^2 + 3$ and the denominator is $g(x) = |x - 5| + |x + 2|$.
For a ... | The domain of the function $h(x) = \frac{x^4 - 4x^2 + 3}{|x - 5| + |x + 2|}$ is determined by the values of $x$ for which the denominator is non-zero. The denominator is $|x - 5| + |x + 2|$. We need to find the values of $x$ for which $|x - 5| + |x + 2| = 0$.

我對Dapper還是新手，我正試圖使用Dapper.SimpleCRUD庫來實現CRUD操作。我有一個叫做"Product"的數據模型，有三個屬性：prodId，prodName和Location。我在Insert操作中遇到了問題，因為prodId在數據庫中是一個Identity Column。我如何在數據庫中指示prodId是一個Identity Column？

**關於 Insert 操作和 Identity Column 的問題**
Dapper.SimpleCRUD 默認情況下並不知道你的 `prodId` 屬性是一個數據庫中的 Identity Column。 你需要明確地告訴它。 SimpleCRUD 使用 **Data Annotations** 來進行屬性配置，其中就包括標識列的配置。

**Insert 操作：處理 Identity Column (prodId)**
Dapper.SimpleCRUD 默認會嘗試插入所有屬性，包括 Identity Column。 由於 Identity Column 是由數據庫自動生成的，所以直接插入會導致錯誤。你需要告訴 Dapper 不要插入 `prodId` 屬性。 有兩種常見的方法可以做到：
1. **使用 `[Explicit]` 屬性:** 將 `prodId` 屬性標記為 `[Explicit]`，這表示 Dapper 不應在插入或更新操作中包含該屬性。

A conservation biologist has been studying an elusive species of bird. Over the past 5 years, the biologist has tracked the bird's population in three different regions.
