Determine whether the following sets are subspaces of r 3 under the operations of addition and scalar multiplication defined on r 3 . justify your answers. (a) w 1 = { ( a 1 , a 2 , a 3 ) β r 3 : a 1 = 3 a 2 and a 3 = β a 2 } (b) w 2 = { ( a 1 , a 2 , a 3 ) β r 3 : a 1 = a 3 + 2 } (c) w 3 = { ( a 1 , a 2 , a 3 ) β r 3 : 2 a 1 β 7 a 2 + a 3 = 0 } (d) w 4 = { ( a 1 , a 2 , a 3 ) β r 3 : a 1 β 4 a 2 β a 3 = 0 } (e) w 5 = { ( a 1 , a 2 , a 3 ) β r 3 : a 1 + 2 a 2 β 3 a 3 = 1 } (f) w 6 = { ( a 1 , a 2 , a 3 ) β r 3 : 5 a 2 1 β 3 a 2 2 + 6 a 2 3 = 0 }
