Matematika Diketahui fungsi f(x) = 2 - 3x, jika x = {-2, -1, 0, * 1, 2}. Maka daerah hasilnya adalah.... O A.{8, 5, 2,-1,-4} O B.{-4, 1, 2, 5, 6} O C.{8, 5, 2, 1,-4} O D. {-4, -1, 2, 5, 6}​

Diketahui fungsi f(x) = 2 - 3x, jika x = {-2, -1, 0, * 1, 2}. Maka daerah hasilnya adalah.... O A.{8, 5, 2,-1,-4} O B.{-4, 1, 2, 5, 6} O C.{8, 5, 2, 1,-4} O D. {-4, -1, 2, 5, 6}​

Penjelasan dengan langkah-langkah:

f(x) = 2 - 3x

x = {-2,-1,0,1,2}

• Menentukan range :

f(-2) = 2 - 3.(-2) = 2 + 6 = 8

f(-1) = 2 - 3.(-1) = 2 + 3 = 5

f(0) = 2 - 3.0 = 2 - 0 = 2

f(1) = 2 - 3.1 = 2 - 3 = -1

f(2) = 2 - 3.2 = 2 - 6 = -4

Range = {8,5,2,-1,-4} Jawabannya A.
