Let O = (0,0), and a = (2, –1) be points in R2. Set G = B (O, 1) = {v = (x, y) € R² : d2(O, v) < 1} H = Bª (a, 1) = {v = (r, y) € R²: d1(a, v) < 1} %3D (a) Describe G and H in terms of (x, y)-curves alone, and where applicable without making use of any absolute value symbol. (b) Give the set S of all possible values of y if v = (y) E H. (c) Sketch G and H in separate Cartesian coordinates systems (r, y), indicating only O, a and all possible r-intercepts and y-intercepts.
