Sorry, I thought you meant (1/2) * (1/2x). It's hard to write maths in this forum.because it was gg(x) and g(x)=1/2x then it will be 1/2(1/2x) cause like the question is gg(x) so then g(x)= 1/2x then g(g(x))= 1/2(1/2x)
srry bout' the wrong information really srry...
If you wrote 1 / [2(1/2x)], like I did in my solutions, you will probably get 1 mark.
