**Characteristics of Polynomial and Rational Functions**

**Left Side:**

**Graph of the function f(x) = 9 - (x - 4)²:**

- The graph is a downward-opening parabola with its peak at a single point, indicating the vertex.

**Vertex:**

- Ordered Pair: (4, 9)

**Axis of Symmetry:**

- Equation of the Line: \( y = 4 \)

**Intercepts:**

- **x-intercepts:**
  - Ordered Pairs: (7, 0) & (1, 0)
  
- **y-intercepts:**
  - Ordered Pair: (0, 7)

**Domain:**

- Interval Notation: (-∞, ∞)

**Range:**

- Interval Notation: (-∞, ∞)

**Maximum Values:**

- Where does \( f \) have a local/relative maximum? 
  - At x = 4
- What is the local/relative maximum value? 
  - 9

**Right Side:**

**Graph of the function f(x) = x² + 6x + 5:**

- The graph is an upward-opening parabola.

**Vertex:**

- Ordered Pair: (Not provided, requires calculation by completing the square or using the formula \( x = -\frac{b}{2a} \))

**Axis of Symmetry:**

- Equation of the Line: (To be calculated)

**Intercepts:**

- **x-intercepts:**
  - Ordered Pairs: (To be calculated using the quadratic formula or factoring)
  
- **y-intercepts:**
  - Ordered Pair: (Not provided, typically x = 0 and solve for y)

**Domain:**

- Interval Notation: (-∞, ∞)

**Range:**

- Interval Notation: (To be determined based on the vertex)

**Minimum Values:**

- Where does \( f \) have a local/relative minimum?
  - (To be determined)
  
- What is the local/relative minimum value?
  - (To be determined)

These characteristics help in understanding the behavior of polynomial functions through their graphs, intercepts, and extremum points.
