The graph you provided shows a straight line, which extends infinitely in both directions. Based on this information, we can determine the domain and range.

• Domain: The domain of a function refers to all the possible x-values that the function can take. For a straight line like this one, which extends infinitely to the left and right, the domain is all real numbers. This is represented as: $\text{Domain} = (-\infty, \infty)$

• Range: The range of a function refers to all the possible y-values that the function can produce. Since the line extends infinitely upwards and downwards along the y-axis, the range also includes all real numbers. This is represented as: $\text{Range} = (-\infty, \infty)$

In summary:

• Domain: $(-\infty, \infty)$
• Range: $(-\infty, \infty)$

Would you like more details or further clarification? Here are some related questions you might find useful:

1. How do you determine the slope of the line from a graph?
2. What is the general form of a linear equation?
3. How do domain and range differ for different types of functions (e.g., quadratic, exponential)?
4. What would the domain and range look like for a vertical or horizontal line?
5. Can a function have a limited domain and range, and how would that affect its graph?

Tip: The domain of a linear function is almost always all real numbers, except for special cases like vertical lines where the x-value is fixed.
