a. f(x) = 2x + 4 dan g(x) = x - 5

     (f + g)(x) = f(x) + g(x)

                       = (2x + 4) + (x - 5)

                       = 2x + 4 + x - 5

                       = 3x - 1

 

b. f(x) = x2 - 2x dan g(x) = x2 + 1

     (f - g)(x) = f(x) - g(x)

                      = (x2 - 2x) - (x2 + 1)

                      = x2 - 2x - x2 - 1

                      = -2x - 1

 

c. f(x) = x - 5 dan g(x) = x + 2

     (f × g)(x) = f(x) ×  g(x)

                       = (x - 5)(x + 2)

                       = x2 + 2x - 5x - 10

                       = x2 - 3x - 10
