Psda pametaan f(x) = -2x +7,jika daerah asalnya {-1,0,1,2,3,4,5},maka daerah hasilnya ?

[ 9, 7, 5, 3, 1, -1, -3]
maaf kalau salah

1. F(x) = -2x+7
F(-1)= - 2(-1)+7
= 2+7
= 9
2. F(0)= -2(0)+7
= 0+7
= 7
3. F(1)= - 2(1)+7
= - 2+7
= 5
4. F(2)= -2(2)+7
= -4+7
= 3
5. F(3) = -2(3)+7
= - 6+7
= 1
6. F(4) = - 2(4)+7
= - 8+7
= - 1
7. F(5) = -2(5)+7
= -10+7
= - 3

Sorry kalo salah. Semoga membantu
