1. The problem statement, all variables and given/known data
i have given following problem.I want to know how find an expression for given graph (that is 1st part).rest of parts i will try my self.but with first part i have no idea how to do it. i have attache the word file


2. Relevant equations



3. The attempt at a solution

i was thinking following

F(y) x/6 y<2
F(y) 1/3 2<y<4
F(y) x/3 - 1 4<y<6
F(y) 1 y>6

I assume the graph is suposed to match up with the numbers that the axes were labeled with, so I would go with your equations.
