The given image contains two functions:

1. $f(x) = \sqrt{x}$
2. $g(x) = -2$

Would you like to explore specific operations involving these functions, such as finding their sum, product, or composition? Or perhaps you'd like to investigate other properties such as domains, ranges, or graphing?

Let me know if you need more details! Here are some related questions to consider:

1. What is the domain of $f(x) = \sqrt{x}$?
2. What is the range of $g(x) = -2$?
3. How would you find $(f + g)(x)$?
4. What is the composition $(f \circ g)(x)$?
5. Can you differentiate or integrate these functions?

Tip: For composite functions like $f(g(x))$, make sure to check the domain restrictions of both functions before calculating.
