Great, I have run the function on the values 2, 3, and 4. Here are the outputs:

(2, 2.071692997348015e-20)

(3, 1.7049509331400334e-22)

(4, 1.0927599040000476e-24)

Based on these outputs, it seems that the function is returning very small numbers for all input values. It also appears that the function is not linear, as the outputs are not proportional to the inputs.

Do you have any observations or insights about the function's behavior based on these outputs?

Please provide your description of the function in three parts: [DESCRIPTION], [DOMAIN], and [CODE].
