**Graphing Transformed Functions**

In this activity, we will use transformations to graph the function and state the domain and range using interval notation.

The function we will be working with is:

\[ y = -\sqrt{x + 2} + 1 \]

**Steps and Transformations:**

1. **Base Function:**
   - The basic function here is \( y = -\sqrt{x} \), which is a reflection of the square root function \( y = \sqrt{x} \) across the x-axis.

2. **Horizontal Shift:**
   - The expression \( x + 2 \) indicates a horizontal shift to the left by 2 units. This transformation moves the graph of \( y = -\sqrt{x + 2} \).

3. **Vertical Shift:**
   - The addition of \( +1 \) at the end of the function raises the graph vertically by 1 unit. So, we get \( y = -\sqrt{x + 2} + 1 \).

Using the transformations, we sketch the graph as follows:

**Graphs and Diagrams Explanation:**

- The coordinate plane is labeled with both x and y axes ranging from -5 to 5.
- The graph starts at \( (-2, 1) \) since at \( x = -2 \), \( \sqrt{0} = 0 \) and \( y = 1 \).
- As \( x \) increases, the function \( y = -\sqrt{x + 2} + 1 \) decreases because of the negative sign before the square root, reflecting the curve downward.

**Domain and Range:**

- The **domain** is the set of all x-values that can be input into the function. Since the inside of the square root \( x + 2 \) must be non-negative, the domain is:
  \[
  x \ge -2 \quad \text{or in interval notation:} \quad [-2, \infty)
  \]

- The **range** is the set of all possible y-values of the function. Given the transformations applied:
  - The highest point on the graph is at \( y = 1 \).
  - As \( x \) increases, \( y \) will continue to decrease indefinitely. Hence, the range is:
  \[
  y \le 1 \quad \text{or in interval notation:} \quad (-
