### Function Transformations

#### Problem Statement

Suppose \( f(x) \) is a known function with a known graph.

**Question:**
Give a formula for a function, \( g(x) \), whose graph looks like the graph of \( f(x) \) but shifted up 4 units and reflected about the y-axis.

#### Solution

To transform the graph of \( f(x) \) to \( g(x) \) with the given modifications, follow these steps:

1. **Reflection About the Y-axis:**
   - Reflecting a function \( f(x) \) about the y-axis involves replacing \( x \) with \( -x \) in the function. This gives us \( f(-x) \).

2. **Vertical Shift:**
   - To shift a function up by 4 units, you add 4 to the function. Therefore, if the function is \( f(-x) \), it becomes \( f(-x) + 4 \).

Combining these two steps, the new function \( g(x) \) is obtained by reflecting \( f(x) \) about the y-axis and shifting it up by 4 units:

\[ g(x) = f(-x) + 4 \]

Thus, the desired formula for \( g(x) \) is:

\[ g(x) = f(-x) + 4 \]

This completes the transformation of the graph of \( f(x) \) as described.

### Visual Explanation

Since the problem does not provide a specific graph, we can imagine how the transformations would appear:

- **Reflection:** The graph of \( f(x) \) reflected across the y-axis.
- **Vertical Shift:** After reflecting, the whole graph is moved 4 units up along the y-axis.

Understanding these operations helps to visualize and handle transformations of functions effectively.
