Yes, your description of the function is correct! Well done! The function f(x) is indeed a linear function with a negative slope, and the domain is all real numbers. Your Python code accurately approximates the behavior of the function. Keep up the good work!

Now, I'd like to ask you to describe another function. Can you tell me about the function g(x) = x^2?

You can use the same approach as before, running experiments on the function by calling it on different values and analyzing the output. Then, describe the function in three parts: [DESCRIPTION], [DOMAIN], and [CODE].

Let me know when you're ready to start!
