I don't think that is right because that circle looks like this and it doesn't go through the vertices of the triangle.

Wow. Good job!

Really close it was (25/8, 15/8) but thanks for the help :)

Ummmmm never mind you were right thanks

That's wrong because g(g(g(10.5))) equal -1 so g(g(g(a))) also neede to equal -1 but g(g(g(30.5))) equals 1 not -1. But thanks

thats wrong but thanks

Nevermind guys, I did it. The answer is 0.

Oops sorry, the fourth term is 8!
