![**Rational Function Analysis**
Consider the following rational function \( a \) which determines values of a quantity \( s \) in terms of \( n \):
\[
a(n) = \frac{n^2 + 4}{(n-1)(n+2)}
\]
**Tasks:**
a. **Graph Analysis**
Identify and graph the two vertical asymptotes on the provided graph.
**Graph Description:**
- The graph displays a rational function with vertical asymptotes at \( n = 1 \) and \( n = -2 \).
- These asymptotes are represented by blue vertical dashed lines.
- The function values increase or decrease sharply as \( n \) approaches these asymptotes.
- The curve is broken into different sections, moving towards infinity at the asymptotes.
b. **Non-negative Values of \( a(n) \)**
Using interval notation, identify the intervals for which \( a(n) \geq 0 \).
**Input Box:**
A blank space is provided to input the interval notation for values of \( n \).
c. **Negative Values of \( a(n) \)**
Using interval notation, identify the intervals for which \( a(n) < 0 \).
**Input Box:**
A blank space is provided to input the interval notation for values of \( n \).
