Diketahui fungsi f(x) = 2 - 4x, jika x =
{-2,-1,0, 1, 2}. Maka daerah hasilnya
adalah....​

f(x) = 2 - 4x

f(-2) = 2 - 4(-2)

= 2 - (-8)

= 10

f(-1) = 2 - 4(-1)

= 2 - (-4)

= 6

f(0) = 2 - 4(0)

= 2 - 0

= 2

f(1) = 2 - 4(1)

= 2 - 4

= -2

f(2) = 2 - 4(2)

= 2 - 8

= -6

maka daerah hasil nya adalah {10, 6, 2, -2, -6}
