**Question:**
Which graph has the following characteristics?

* Three real zeros
* As \( x \to -\infty \), \( f(x) \to -\infty \)
* As \( x \to \infty \), \( f(x) \to \infty \)

**Options:**
* Option 1: A graph where the curve crosses the x-axis at three points and the end behavior is as described.
* Option 2: A graph where the curve crosses the x-axis at three points and the end behavior is as described.
* Option 3: A graph where the curve crosses the x-axis at three points and the end behavior is as described.
* Option 4: A graph where the curve crosses the x-axis at three points and the end behavior is as described.

### Graph Descriptions:

**Option 1:**
A polynomial curve crossing the x-axis thrice, moving down towards \( -\infty \) as \( x \) approaches \(  -\infty \), and moving up towards \( \infty \) as \( x \) approaches \( \infty \).

**Option 2:**
A polynomial curve crossing the x-axis thrice, moving down towards \( -\infty \) as \( x \) approaches \(  \infty \), and moving up towards \( \infty \) as \( x \) approaches \( -\infty \).

**Option 3:**
A polynomial curve crossing the x-axis thrice, moving down towards \( -\infty \) as \( x \) approaches \(  -\infty \), and moving up towards \( \infty \) as \( x \) approaches \( \infty \).

**Option 4:**
A polynomial curve crossing the x-axis thrice, moving up towards \( \infty \) as \( x \) approaches \(  -\infty \), and moving down towards \( -\infty \) as \( x \) approaches \( \infty \).

**Correct Answer:**
The correct answer to the question is **Option 3**. This graph meets the criteria of having three real zeros and exhibiting the correct end behavior as specified in the question.
