each part below, indicate (by making suitable arguments) whether the following sets are open (yes/no), closed
yes/no), and bounded (yes/no). Hint: You should probably graph the following sets.
The straight line connecting the points (a, b) and (c,d) (including the endpoints) in R² where a < b <c<d.
The set consisting of {(x, y) € R²:0 ≤ x ≤ 2,0 ≤ y ≤ 2} left over after excluding the set {(x,y) € R²:0.5 <
x < 1.5, 0.5 <y< 1.5}.
