Transcribed Image Text:**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)
