Thread: identify function

Hello,

just for the fun of it, I have been wondering if someone can identify the yellow function / of power usage in Fig. 6.1 Peak transitional thresholds on Ex Astris Scientia - Warp Propulsion - 6 Warp Speed Measurement
so what is y=f(x)=?

Best regards,
Hando

Sorry about the image, i did not realize that it would forbid it.

I see nothing at that website.

Sorry, it was a direct link. I have corected it.
