Here is the graph - 2 points

NOTE: I have not fully got my head around how to do this without graphing it.

For -4 ≤ x ≤ -1   --->  f(x) = -(3/4)x + 1/4   --->  f( f(x) ) =  -(3/4)( -(3/4)x + 1/4) + 1/4 = (9/16)x + 1/16

--->  3  =  (9/16)x + 1/16   --->   x  =  47/9   (not in the domain)

For -1 ≤ x ≤ 3   --->  f(x) = x + 2   --->   f( f(x) )  =  (x + 2) + 2  =  x + 4

--->   3  =  x + 4   --->  x = -1      --->  one point

For 3 ≤ x   --->  f(x) =  -x + 8   --->   f( f(x) )  =  -(-x + 8) + 8  =  x - 8

--->   3  =  x - 8   --->  x = 11      --->  one point

Sorry to say that this answer was wrong. Can you see if there was another answer to this possibly?
