Question

Jika f(x)=5x-1 dengan domain {2,4,6,8}
,tentukan daerah hasilnya!

Answer 1

X = 2 jadinya f(2) = 5(2) -1 = 10-1 = 9
x = 4 jadinya f (4)= 5(4) -1 = 20-1 = 19
x = 6 jadinya f (6) = 5(6) -1 = 30-1 = 29
x = 8 jadinya f(8) = 5(8) -1 = 40 -1 = 39
jadi kodomainnya {9,19,29,39}

semoga bermanfaat
