Question

Tentukan f(X) = 8-2X dengan daerah hasil asal ( -3,-2,-1,0,1,2,3) daerah hasil fungsi tersebut adalah

Answer 1

F(x) = 8-2x       x = {-3,-2,-1,0,1,2,3)
f(-3)= 14
f(-2)=12
f(-1)=10
f(0)=8
f(1)=6
f(2)=4
F(3)=2

range/daerah hasil = 14,12,10,8,6,4,2

Answer 2

F(-3) = 8-2(-3) = 14 f(-2) = 8-2(-2) = 12 f(-1)= 8-2(-1)= 10 f(0) = 8-2(0)= 8 f(1) = 8-2(1)= 6 f(2)= 8-2(2) = 4 f(3) = 8-2(3) = 2 Rf : {2,4,6,8,10,12,14}
