Based on the input-output pairs, I can make an initial description of the function's behavior:

[DESCRIPTION]: The function seems to tend towards being a very small negative number over the domain of input provided. It appears to have a minimum around x = 5.

Now, I will run experiments within shorter intervals to find any unexpected behavior.

COMMAND: PYTHON(./temp7/function.py -10 -8 -6 -4 -2 0 2 4 6 8 10)
