Given this equation, find the answer

Step-by-step explanation:

                          1

Because f(x) =

                         x - 4

                   1

f(x + h) =

               x + h - 4

and so:

                           1               1

                        -

f(x + h) - f(x)      x+h - 4      x - 4                        -h                               -1

= =   =

         h                             h                     h[x - 4][x + h - 4]        [x - 4][x + h - 4]
