The function you provided is:

\[
f(x) = \frac{1}{x^2 + 2x - 3}
\]

### Steps to Analyze the Function:
1. **Factor the denominator**:
   The denominator is a quadratic expression \( x^2 + 2x - 3 \), which can be factored as:
   \[
   x^2 + 2x - 3 = (x + 3)(x - 1)
   \]
   Thus, the function can be rewritten as:
   \[
   f(x) = \frac{1}{(x + 3)(x - 1)}
   \]

2. **Domain of the function**:
   The domain is all real values of \( x \) except where the denominator is zero. To find these points:
   \[
   (x + 3)(x - 1) = 0
   \]
   Solving for \( x \), we get \( x = -3 \) and \( x = 1 \). Therefore, the domain is:
   \[
   x \in (-\infty, -3) \cup (-3, 1) \cup (1, \infty)
   \]

3. **Asymptotes**:
   - **Vertical Asymptotes**: Occur at \( x = -3 \) and \( x = 1 \), where the denominator becomes zero.
   - **Horizontal Asymptote**: Since the degree of the numerator (constant) is less than the degree of the denominator (quadratic), the horizontal asymptote is at \( y = 0 \).

4. **Behavior around the asymptotes**:
   The function will approach positive or negative infinity as \( x \) gets close to \( -3 \) and \( 1 \), depending on the direction of approach.
