f(-3) = 3×(-3)+10
= -9+10
= 1
f(-2) = 3×(-2)+10
= -6+10
= 4
f(-1) = 3×(-1)+10
= -3+10
= 7
f(0) = 3×(0)+10
= 0+10
= 10
jadi, daerah hasil f= 1,4,7,10
JAWAB
domain x = {-3,-2,-1,0}
fungsi pemetaan → f(x) = 3x + 10
maka
◆f(-3) = 3.(-3) + 10 = -9+10 = 1
◆f(-2) = 3.(-2) + 10 = -6+10 = 4
◆f(-1) = 3.(-1) + 10 = -3+10 = 7
◆f(0) = 3.(0) + 10 = 0+10 = 10
Jadi daerah hasil = {1,4,7,10}
