### Evaluating Functions Using Graphs

#### Understanding the Graphs

- **Graph of \(y = f(x)\)**
  - This graph displays a piecewise linear function.
  - Coordinates of notable points:
    - \((0, 4)\)
    - \((1, 2)\)
    - \((2, 1)\)
    - \((3, 3)\)
  - The graph starts at point \((0, 4)\), undergoes a descending slope to \((2, 1)\), and then ascends again at point \((3, 3)\).

- **Graph of \(y = g(x)\)**
  - This graph represents another piecewise linear function.
  - Coordinates of notable points:
    - \((0, 4)\)
    - \((1, 3)\)
    - \((2, 2)\)
    - \((3, 1)\)
    - \((4, 0)\)
  - The graph starts at point \((0, 4)\) and continuously decreases to \((4, 0)\).

#### Tasks

1. **Evaluate \( (f - g)(1) \)**
2. **Evaluate \( (fg)(1) \)**

__Solution Steps:__

- To find \((f - g)(x)\) at \(x = 1\):
  - Determine \(f(1)\) from the graph of \(y = f(x)\).
  - Determine \(g(1)\) from the graph of \(y = g(x)\).
  - Compute \((f - g)(1) = f(1) - g(1)\).

- To find \( (fg)(x) \) at \( x = 1 \):
  - Determine \( f(1) \) from the graph of \( y = f(x) \).
  - Determine \( g(1) \) from the graph of \( y = g(x) \).
  - Compute \((fg)(1) = f(1) \cdot g(1)\).

Below the graphs, there are fields to fill in the values of \((f - g)(1)\) and \((fg)(1)\):

(a) \( (f - g)(1) \) ___________________

(b) \( (fg)(1) \) ___________________
