A thin equilateral triangular block of the side length 1 unit has its face in the vertical xy-plane with vertex V at the origin. Under the influence of gravity, it will rotate about V until a side hits the x-axis floor (see diagram). Let x denote the inital x-coordinate of the midpoint M of the side opposite V, and let f(x) denote the final x-coordinate of the point. Assume that the block balances when M is directly above V.

(a) Determine the domian and range of f

(b) Where on the domain is f discontinuous

(c) Identify any fixed points of f

I have no clue how to go about answering the question. Any help/hints on solving each part would be great, thanks.
