di ketahui f (x) = 5-2x dengan daerah asal (-2,-1,0,1,2).daerah hasil fungsi tersebut adalah.....

F(-2) = 5-2×(-2)
F(-2) = 5+4
F(-2) = 9

F(-1) = 5-2×(-1)
F(-1) = 5+1
F(-1) = 6

F(0) = 5-2×0
F(0) = 5-0
F(0) = 5

F(1) = 5-2×(1)
F(1) = 5-2
F(1) = 3

F(2) = 5-2×2
F(2) = 5-4
F(2) = 1

Jadi, daerah fungsi {9,65,3,1}
