    e^2x^2+4x=y

    dy/dx=[4x+4]e^2x^2+4x right?

    OK. Anything of the form e^f(x) has derivative f'(x)*e^f(x). In your case, f(x) = 2x^2 + 4x and so f'(x) = 4x + 4.

    depends on whether this is meant to be:

    y = 4x + e^2(x^2)

    or y = e^(2(x^2)+4x), which I think is how Jonny interpreted it.
