# Solve: Topology Induced

Question: Find the interior, the closure, the accumulation points, the isolated point and the boundary points of the following sets.

a) X = [(0,1) in R with the topology induced by d(x,y) = |x-y|]

b) X = Q in R with the same topology as above.

c) X = {(x,y) : |y| < x^2} U {(0,y), y E R} in R^2, with the topology induced by the norm || (x,y) || = max {|x|, |y|}.

d) Same as in c), but the topology is now generated by the distance d ((x,y), (x_1,y_1)) = |x - x_1| + max {|y|, |y_1|}
