Question: Let T = { hMi | M is a TM that accepts w R whenever it accepts w } . Note that w R denotes

Let T ={hMi | M is a TM that accepts w
R whenever it accepts w}. Note that w
R denotes
the reverse of string w. Thus, hMi in T iff TM M has the property that for every input string
w, M either accepts both w and w
R or M does not accept w and w
R.
Show that T is undecidable. (15 points)
