im confused about 2biii, cuz the inverse of t gives a transformation of a reflection in the line y=x, but the mark scheme says reflection in the line y=-x, which is the answer for 2bi also

From (ii) it is clear that .

In (iii) all you need to do is then to realise that transformation of the inverse is that of the original. The original is clearly a reflection in the line y=-x

ahh okk
but if you actually work out T inverse you get a different transformation? why is that x
