Example:  If f(x) = -x + 8, then f(a) = -a + 8.

Thus,                                       f(x+k) = -(x+k) + 8 = -x + 8 + k, or f(x) + k
                                                   (after rearrangement)

The first statement is true.  Check out the other 3 statements.  Are they true or not?
