Diketahui f(x)=5-2x dengan daerah asal {-2,-1,0,1,2}.Daerah Hasil Fungsi Tersebut Adalah...

f(-2)= 5-2x
          5-2(-2)
          5-4
       = 1
f(-1) = 5-2(-1)
           5-2
        = 3
f(0) = 5-2(0)
         5-0
      = 5
f(1) = 5-2(1)
         5-2
      = 3
f(2) = 5-2(2)
         5-4
       =1




Semoga membantu

f(x) = 5 - 2x
f(-2) = 5 - 2(-2) = 5- (-4) = 9
f(-1) = 5 - 2(-1) = 5 - (-2) = 7
f(0) = 5 - 2(0) = 5 - 0 = 5
f(1) = 5 - 2(1) = 5 - 2 = 3
f(2) = 5 - 2(2) = 5 - 4 = 1

Daerah Hasil : {9,7,5,3,1}
