Dik fungsi F = X → 4X – 1. tentukan nilau fungsi F untuk X = -5, -3, -1, 0, 2, 4 dan 10

F(x) = 4x – 1

f(-5) = 4x – 1
       = 4(-5) – 1 
       = - 20 – 1 = -21

f(-3) = 4x – 1
       = 4(-3) – 1
       = – 12 – 1 = -13

f(-1) = 4x – 1
       = 4(-1) – 1
       = - 4 – 1 = -5

f(0) = 4x – 1
      = 4(0) – 1
      = 0 – 1 = -1

f(2) = 4x – 1
     = 4(2) – 1
     = 8 – 1 = 7

f(4) = 4x – 1
      = 4(4) – 1
      = 16 – 1 = 15
 
f(10) = 4x – 1
       = 4(10) – 1
       = 40 – 1 = 39
