Construct the intersection graph of these collections of

Question

1) Construct the intersection graph of these collections of sets:

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, . . .}

2) Construct the intersection graph of these collections of sets:

A₁ = {x | x < 0}
A₂ = {x | -1 < x < 0}
A₃ = {x | 0 < x < 1}
A₄ = {x | -1 < x < 1}
A₅ = {x | x > -1}
A₆ = R
