Here's a question from a past paper
I have attempted the first part and my values are:
K = +8 or -8 C = 2
Whereas the answer in the marking scheme states K = 32 and C = 2
Is there a mistake in the marking scheme because the value of K can't be 32 if the value of C is 2 ... right?
My equation of the curve comes out to be
Thanks, sorry for the mix up, as the question was so basic I thought it belonged in the basic forums. Nevertheless, thanks for moving it, although I don't think this belongs in the university level calculus, maybe in the high-school calculus forum.
