**Title: Understanding Domain and Range Using Interval Notation**

**Introduction:**

In this exercise, we explore how to determine and express the domain and range of a function using interval notation. Understanding these concepts is fundamental in analyzing the behavior of functions.

**Task Description:**

- **Objective:** Write the domain and range of the function using interval notation.

**Graph Analysis:**

The graph provided shows a parabolic function. Here’s a detailed explanation of the graph:

- **Axes:** The graph features a standard Cartesian coordinate system with the x-axis and y-axis both ranging from -5 to 5.

- **Curve:** The function is a downward-opening parabola.
  - The left end of the parabola slightly touches the y-axis at approximately y = 3.
  - The right end of the parabola is open and heads towards x = 3.

**Determining Domain and Range:**

- **Domain:** The set of all possible x-values that the function can take.
  - For this graph, the x-values range from -3 to 3, inclusive of -3 and exclusive of 3.
  - **Interval Notation:** \([-3, 3)\)

- **Range:** The set of all possible y-values that the function can output.
  - The highest point of the parabola is at y = 3, and it opens downward without extending below y = 1.
  - **Interval Notation:** \([1, 3]\)

**Instructions:**

- **Domain:** Enter \([-3, 3)\)
- **Range:** Enter \([1, 3]\)

**Conclusion:**

Understanding how to find and express the domain and range using interval notation helps clarify the input and output limits of functions, a crucial skill in mathematical analysis.

**Note:**

Ensure to show your work and explain how you arrived at your answers for a comprehensive understanding.
