Question

Pemetaan f(x)=2x-6 dari himpunan A={-2,-1,0,1,2,3,} ke himpunan B. Tentukan bilangan daerah hasil!

Answer 1

Verified answer

F(x)=2x-6

Daerah hasil
F(-2) = 2×(-2)-6
= -4-6
= -10
F(-1) = 2×(-1)-6
= -2-6
= -8
F(0) = 2×0-6
= 0-6
= -6
F(1) = 2×1-6
= 2-6
= -4
F(2) = 2×2-6
= 4-6
= -2
F(3) = 2×3-6
= 6-6
= 0

Jadi, daerah hasil = {-10,-8,-6,-4,-2,0}

Semoga membantu

Answer 2

F(x) = 2x - 6
domain = {-2,-1,0,1,2,3}
kodomain = {........}

f(-2) = 2(-2)-6 = -4-6 = -10
f(-1) = 2(-1)-6 = -2-6 = -8
f(0) = 2(0)-6 = 0-6 = -6
f(1) = 2(1)-6 = 2-6 = -4
f(2) = 2(2)-6 = 4-6 = -2
f(3) = 2(3)-6 = 6-6 = 0

kodomain ={-10,-8,-6,-4,-2,0}
