The graph shows a function that starts at $y = 2$ and increases indefinitely as it moves to the right. This suggests that the function has a minimum $y$-value of 2 and continues upward without bound. Therefore, the range of the function is:

$[2, \infty)$

This means that the $y$-values begin at 2 and increase towards infinity.

Would you like further explanation or details on this? Here are five follow-up questions for you:

1. What is the domain of this function based on the graph?
2. How would you determine the domain and range for more complex functions?
3. What types of functions have a range that extends to negative infinity?
4. How does the behavior of the graph at $x = 0$ affect its range?
5. What does the range of a quadratic function typically look like?

Tip: To determine the range of any function, focus on the possible output values (or $y$-values) it can take as $x$ varies.
