# Looking for a function

I'm looking for a curve that's roughly shaped like this:

Sigmoid alone won't do the trick because I need two bends in the same direction (and also lying on its side, but that part would probably be doable). I'm trying to concoct something together, but I suck at this stuff...

Wouldn't a combination of a linear function and a sine work there? Otherwise, if you just need to fit it to some data points, what about using a bezier curve?

there is a Bezier Curve function in Blender

Your right end looks very steep, so maybe a square root together with the sin(x)-x would help?
Here is $$\sqrt{-\sin^2 \left(x-1\right) - x + 5 }$$
The sqrt makes the end steep, the square on the sine makes it more "wavy".
