The graph shown represents a linear function. To answer the questions provided, we can proceed step by step.

1. Domain and Range:

• Domain: The domain of a function is the set of all possible input values (x-values). For this linear function, the graph extends infinitely in both directions along the x-axis, so the domain is all real numbers: $\text{Domain}: (-\infty, \infty)$

• Range: The range is the set of all possible output values (y-values). Similarly, the line extends infinitely in both directions along the y-axis, so the range is also all real numbers: $\text{Range}: (-\infty, \infty)$

2. Determining if the Function is Invertible:

A function is invertible if it is one-to-one, meaning that each x-value maps to exactly one unique y-value, and no horizontal line crosses the graph more than once. Since this is a linear function, and linear functions are always one-to-one, the function is invertible.

3. Domain and Range of the Inverse:

For an invertible function, the domain and range of its inverse are swapped:

• The domain of the inverse is the range of the original function.
• The range of the inverse is the domain of the original function.

Since both the domain and range of the original function are all real numbers, the domain and range of the inverse will also be: $\text{Domain of the inverse}: (-\infty, \infty)$ $\text{Range of the inverse}: (-\infty, \infty)$

Tip: For linear functions, the slope gives important information about the function's behavior—whether it increases or decreases and how steeply.
