               4                                     2



 Ask yourself, “What can I do to 1 to get to -1,
                                 2 to get to 0….?

 Ask yourself, “What can I do to 1 to get to -1,
                                 2 to get to 0….?

 Subtract 2 from each input value.

 Ask yourself, “What can I do to 1 to get to -1,
                                 2 to get to 0….?

 Subtract 2 from each input value.

 So, f(x) equals x minus 2.

 Subtract 2 from each input value.

 So, f(x) equals x minus 2.

 f(x) = x – 2
