Given a function f(x)= \frac{2x^2-5x+3}{x^2+5x}


(i) Find the horizontal and vertical asymptotes.

To find the horizontal and vertical asymptotes of the function \( f(x) = \frac{2x^2 - 5x + 3}{x^2 + 5x} \), we follow these steps:

### Horizontal Asymptotes
Horizontal asymptotes are found by considering the limits of \( f(x) \) as \( x \) approaches \( \infty \) or \( -\infty \).

1. **Degree of the numerator (N) and denominator (D):**
   - Degree of \( N(x) = 2x^2 - 5x + 3 \) is 2.
   - Degree of \( D(x) = x^2 + 5x \) is 2.

2. **Comparing degrees:**
   - If the degrees of the numerator and denominator are equal, the horizontal asymptote is given by the ratio of the leading coefficients.

Here, both degrees are 2, and the leading coefficients are:
- Numerator: 2
- Denominator: 1

Therefore, the horizontal asymptote is:
\[ y = \frac{2}{1} = 2 \]

### Vertical Asymptotes
Vertical asymptotes occur where the denominator is zero and the numerator is non-zero.

1. **Set the denominator to zero:**
   \[ x^2 + 5x = 0 \]
   \[ x(x + 5) = 0 \]

2. **Solve for \( x \):**
   \[ x = 0 \]
   \[ x = -5 \]

### Conclusion
The vertical asymptotes are at \( x = 0 \) and \( x = -5 \).
The horizontal asymptote is at \( y = 2 \).
