Can somebody help me with these three graphs I am unsure on how to put them together.

The intersection graph of a collection of sets A1, A2,....,An is the graph that has a vertex for each of these sets and has an edge connecting the vertices representing two sets if these sets have a nonempty intersection.

Construct the intersection for these collections of sets:

a) A1={0,2,4,6,8}, A2={0,1,2,3,4}, A3={1,3,5,7,9}, A4={5,6,7,8,9}, A5={0,1,8,9}

Construct the intersection for these collections of sets:

b) A1={...,-4,-3,-2,-1,0}, A2={...,-2,-1,0,1,2,...}, A3={...,-6,-4,-2,0,2,4,6,...}, A4={...,-5,-3,-1,1,3,5,...}, A5={...,-6,-3,0,3,6,...}

Construct the intersection for these collections of sets:

c) A1={x|x<0}, A2={x|-1-1}, A6=R
