Question

Tentukan range dari f(x) =3x - 5 jika domainya Df ={-4, -3, -2, -1, 0, 1, 2, 3}!
tolong bantu,, makasi

Answer 1

F(x)=3x-5   *Masukan domain fungsi itu ke dalam variabel x
f(-4)=3(-4)-5
      = -12-5
      = -17
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
f(3) = 3(3)-5
      = 9-5
      = 4
