The graph shown is a portion of a function that starts at $x = 2$ and increases towards the right.

Domain:

The domain of a function refers to the set of all possible input values (or $x$-values) for which the function is defined.

In this case, the function begins at $x = 2$ and continues indefinitely to the right, covering all values greater than or equal to 2. Therefore, the domain is:

$\text{Domain} = [2, \infty)$

Here are 5 related questions to expand your understanding:

1. How do you determine the range of this function from the graph?
2. What is the significance of the arrow on the graph?
3. Can a function have multiple domains?
4. What types of functions typically have restricted domains?
5. How would the domain change if the graph moved left?

Tip: The domain is often limited by the real-world context of the problem or by restrictions such as square roots or divisions by zero in the function.
