1. Explain why (a) e-2-in = (62 - 8)4 (b ) = 10. (V2i) 6(3 + 42) 3 2. (a) The set A is illustrated below. -5 -4 -3 -2 -1 0 1 2 3 4 5 (i) Write A using interval notation. (ii) Write A in two different ways, using set notation, (i.e. in the form {x E .. . |... }). (b) The set B is illustrated below. (i) Write set B as a list, for example, {-1, 0, 1, 2, 3} (ii) Write B using set notation of the form {r e . . . |. . .}
