The domain of the function appears to be [-128, 128]. There doesn't seem to be any unexpected behavior within this interval, but we can narrow it down further.

Let's calculate the slope and the intercept of the function by comparing two data points. We can take the data points (0, 8) and (32, 209.6) to do this:

slope = (209.6 - 8) / (32 - 0)
intercept = 8

slope = 6.3
intercept = 8

Now we can write the Python code that approximates the behavior of the function.
