fungsi f : - 5x+1 mempunyai daerah asal {0,1,2,3,4} Tentukan : a. Rumus fungsi b. Daerah hasil c. Himpunan pasangan berurutan

a. rumus fungsi
f(x) = -5x + 1

b. Daerah hasil
daerah asal = {0,1,2,3,4}
f(0) = -5(0) + 1 = 1
f(1) = -5(1) + 1 = -4
f(2) = -5(2) + 1 = -9
f(3) = -5(3) + 1 = -14
f(4) = -5(4) + 1 = -19

daerah hasil = {1, -4, -9, -14, -19}

c. himpunan pasangan berurutan
hp = {(0,-1) , (1,-4) , (2,-9) , (3,-14) , (4,-19)}
