Question

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

Answer 1

X = {-3, -2, -1, 0, 1, 2, }
f : x = 3x-5
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=0-5=-5
f (1) = 3 (1)-5= 3-5=-2
f (2) = 3 (2)-5= 6-5=1
hasil fungsi f={-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
       =0-5
       =-5
f (1) = 3 (1)-5
       = 3-5
       =-2
f (2) = 3 (2)-5
      = 6-5
      =1
Hp={-14, -11, -8, -5, -2, 1}
