**Domain and Range Analysis with Graph Interpretation**

**Introduction:**
In this lesson, we will analyze the given graph to determine its domain and range. Additionally, we will use the graph to find specific function values and identify any x-values for which the function equals 4.

**Domain and Range:**
The domain of a function is the set of all possible input values (x-values) for which the function is defined. The range is the set of all possible output values (y-values) the function can take.

**Graph Explanation:**
The graph provided is a piecewise linear function depicted in a coordinate plane. The x-axis represents the input variable \(x\), and the y-axis represents the output variable \(y\). The graph has distinct line segments connecting several key points.

Key Points on the Graph:
- (-2, 0)
- (0, 8)
- (2, 0)
- (2, 10)

**Detailed Questions:**
(a) **Find \( f(-2) \):**
   Locate x = -2 on the x-axis and find the corresponding y-value on the graph. \( f(-2) = 0 \).

(b) **Find \( f(0) \):**
   Locate x = 0 on the x-axis and find the corresponding y-value on the graph. \( f(0) = 8 \).

(c) **Find \( f\left(\frac{1}{2}\right) \):**
   Locate x = 0.5 (since \(\frac{1}{2}\) is equal to 0.5) on the x-axis and find the corresponding y-value on the graph. \( f(0.5) = 6 \).

(d) **Any values of x such that \( f(x) = 4 \):**
   Find all x-values where the graph intersects the line y = 4.
   - From the graph, we can see that at \( x = -1 \) and \( x = 1.5 \), \( f(x) = 4 \).

*Graphical Representation Explanation:*
- The x-axis ranges from -2 to 2.
- The y-axis ranges from 0 to 10.
- The function starts at point (-2, 0), rises to (0, 8), drops to (2, 0), and rises again to (2, 10).
