GCSE 9-1 paper mark scheme is wrong?

http://qualifications.pearson.com/content/dam/pdf/GCSE/mathematics/2015/specification-and-sample-assesment/GCSE-Mathematics-2015-SAM.pdf

So I'm doing the second paper higher tier, (second last paper on that pdf)

Page 137 of pdf, question 19 of paper 2 higher.

Question b is a transformation question, I applied the transformation but the mark scheme says the wrong y value.

The point (-2,0) applied to the transformation -f(x) + 3 is surely (-2, 3) I don't see it any other way but the mark scheme says (-2,2)?

Yes there is a mistake in the mark scheme.

It would be a good exercise for you if you work out using the original graph what $f(x)$ is. Then apply the transformation algebraically and verify that (-2, 2) does not lie on this transformed graph.

I'll help with the other question later when I have time, if it hasn't been answered already. Tag/quote me if I forget.

Ok don't know why or how the mark scheme can be wrong.

Did you check the triangle question as well?

I simply don't understand how they got 130 as the answer?

I make it 22.6 (3sf), and even in the ambiguous case the 130 doesn't add up.
