Why have they got d/dx (2xy2) ? Surely it should be d/dx (4xy2)? I mean the coefficient is 4x and the y term is y2 ?

Because that would be wrong
Can you differentiate
wrt x
If you can you will see that it is wrong

From the book:
How do we know whether f(x) = 4x or just x ?
I'm having trouble spotting what is f(x) and what is y etc

Since you can take constants out of the differentiation, it doesn't matter. But if you let f(x)=x then you have to multiply your answer by 4 afterwards.

This differential equation is not of that type
