f:x--> 5 - x jika daerah asalnya (-3,-2,-1,0.1,2,3,4) maka daerah hasilnya

f(x)=5-x
f(-3)=5-(-3)=5+3=8
f(-2)=5-(-2)=5+2=7
f(-1)=5-(-1)=5+1=6
f(0)=5-0=5
f(1)=5-1=4
f(2)=5-2=3
f(3)=5-3=2
f(4)=5-4=1
daerah hasil={8,7,6,5,4,3,2,1}

f(X)= 5-X
MAKA :
F(-3) = 5 - (-3) = 8
F(-2) = 5 - (-2) = 7
F(-1) = 5 - (-1) = 6
F(0) = 5 - 0 = 5
F(1) = 5-1=4
F(2)= 5-2 = 3
F(3) = 5-3 = 2
F(4) = 5-4 =1
MAKA DAERAH HASIL {8,7,6,5,4,3,2,1}
