The image shows a mathematical function notation, which appears to be:

$f(x) = 1 + \cos(x)$

It seems like there might also be a question related to finding the range, domain, or some other property of this function, though it's not fully visible.

Would you like help analyzing specific properties of $f(x) = 1 + \cos(x)$, such as finding the range, domain, or calculating derivatives?

Here are five related questions that build on this function:

1. What is the domain of the function $f(x) = 1 + \cos(x)$?
2. What is the range of $f(x) = 1 + \cos(x)$?
3. How does $f(x) = 1 + \cos(x)$ behave as $x$ approaches positive and negative infinity?
4. What is the derivative of $f(x) = 1 + \cos(x)$ with respect to $x$?
5. How would you sketch the graph of $f(x) = 1 + \cos(x)$?

Tip: Remember that the range of a cosine function, shifted or scaled, depends on its amplitude and any vertical shifts applied.
