What does this sign say?

Factual Questions

At the science march in Chicago a week ago, I saw a woman holding the sign shown in this photo. (There’s only one pic in the album – I think you have to click on it to see it all.)

I asked her about it, and she said that if I input the equations into a graphing calculator, I could see what her sign actually said. Sadly, I lack both decent math capabilities and a graphing calculator. But I know there are many here with both, so I’m asking you:

What does the sign say?

Anarchy symbol I guess.
Here’s google rendering all but the last line, finishing the A.

Looks like an anarchy symbol to me:

https://www.wolframalpha.com/input/?i=graph+(2%2B(-(x-2)^2%2B1)%5E.5),+((2-(-(x-2)%5E2%2B1)%5E.5)),(3x-3),(-3x%2B9),(.2x%2B1.7))

ETA: Darn it, beaten to it by Folly. I actually did the same thing with Google, but typed in “graph (2+(-(x-2)^2+1)^.5), ((2-(-(x-2)^2+1)^.5)),(3x-3),(-3x+9),(.2x+1.7)” and found out it will work, but only with 4 elements, so I had to delete one.

Here’s a better visualization. Feel free to change XMin and YMin to 0 for an even closer look.

Thanks. Now it makes sense.
