Pada pemetaan f : 5 - x, jika daerah asalnya {-3,-2,-1,0,1,2,3,4}, maka daerah hasil adalah... a. {-1,-2,-3,-4,-5,-6,-7,-8} b. {1,2,3,4,5,6,7,8} c. {-2,-3,-4,-5,-6,-7,-8,-9} d. {2,3,4,5,6,7,8,9}

F: 5- x ⇒ x = -3 = 5-(-3) = 8 x = -2 = 5-(-2) = 7 x = -1 = 5-(-1) = 6 x = 0 = 5-(0) =5 x = 1 =5-(1) =4 x = 2 = 5-(2) = 3 x = 3 =5-(3) = 2 x = 4 =5-(4) = 1 daerah hasil adalah = {8,7,6,5,4,3,2,1}
x = -2 = 5-(-2) = 7
x = -1 = 5-(-1) = 6
x = 0 = 5-(0) =5
x = 1 =5-(1) =4
x = 2 = 5-(2) = 3
x = 3 =5-(3) = 2
x = 4 =5-(4) = 1
daerah hasil adalah = {8,7,6,5,4,3,2,1}
