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]

ASSUMING THAT THE FUNCTION IS SYMMETRICAL:

This graph is identical if it is the same when "reversed." x represents the coordinate in the x-axis, while f(x) represents the coordinate in the y-axis.

If

x = -1, then f(x) = 1

x = -3, then f(x) = 2

x = -5, then f(x) = 3

x = -6, then f(x) = 3
