Question

Fungsi f:x -> 3x-5 dengan x€ {-3,-2,-1,0,1,2}. daerah hasil fungsi f adalah

Answer 1

F(x)=3x-5
f(-3)=3(-3)-5=-14
f(-2)=-11
f(-1)=-8
f(0)=-5
f(1)=-2
f(2)=1
daerah hasilnya adalah {-14,-11,-8,-5,-2,1}

Answer 2

F(x) = 3x -5
f(-3) = 3(-3) -5
         = -9 -5 = -14
f(-2) = 3(-2) -5
       = -6 -5 = -11
f(-1) = 3(-1) -5
       = -3 -5 = -8
f(0) = 3(0) -5
       = -5
f(1) = 3(1) -5
     = 3 -5 = -2
f(2) = 3(2) -5
       = 6 -5 = 1
Jadi, daerah hasil fungsinya = {-14, -11, -8, -5, -2, 1}.
