Hi there,
I'd really appreciate some help!
I have the following problem:
I understand that f'x = 9x^2 + 3, but I don't see how this helps.
I also understand that the integral of f'x/fx = ln|f(x)|+C and I'm assuming this is useful for this problem.
I know that if I take out a factor of 3 from f'(x) then I'm left with the same expression as is on the top of the fraction I'm asked to integrate - but if I take out a factor of 3 from the top of the fraction, don't I also have to then take a factor of 3 from the bottom of the fraction?
I hope I've made sense, and thanks in advance to anyone who might be able to help.
