![### Graph Analysis for Mathematical Expressions
Use the graph to evaluate each expression.
#### Expressions to Evaluate:
(a) \( (f + g)(-2) \)
(b) \( (f - g)(1) \)
(c) \( (fg)(0) \)
(d) \( \left(\frac{f}{g}\right)(1) \)
#### Detailed Graph Description:
- **Graph Axes:**
- The horizontal axis is labeled as \( x \).
- The vertical axis is labeled as \( y \).
- **Functions:**
- The function \( y = f(x) \) is represented by a blue upward-opening parabola centered at the origin.
- The function \( y = g(x) \) is depicted as a purple downward-sloping line crossing the \( y \)-axis.
- **Graph Points and Lines:**
- The parabola \( y = f(x) \) crosses the \( y \)-axis at \( y = 4 \) and the \( x \)-axis at \( x = \pm 2 \).
- The line \( y = g(x) \) crosses the \( y \)-axis at a positive value and the \( x \)-axis at a value less than \( -2 \).
### Task:
Evaluate each expression using the provided graph.
#### Example:
(a) \( (f + g)(-2) = \) [Evaluate by adding the values of \( f(-2) \) and \( g(-2) \) from the graph]
Fill in the values for each part using the graph's information.
