pemetaan f (x) = 2x - 6 dati himpunan A = {-2, -1, 0, 1, 2, 3, 4} ke himpunan B. tentukan bilangan hasil daerah

A = { -2, -1,0,1,2,3,4 } f(x) = 2x - 6
f (-2) = 2.-2 -6 = -4 -6 = -10
f (-1) = 2.-1 - 6 = -2 -6 = -8
f (0) = 2.0 - 6 = -6
f (1) = 2.1 - 6 = - 4
-1f (2) = 2.2 - 6 = 4 -6 = -2
f (3) = 2.3 - 6 = 6 - 6 = 0
f (4) = 2.4 - 6 = 8 - 6 = 0
B = { -10, -8, -6, -4, -2, 0, 2 }
