I think there is something that I am missing because my answer is turning out to be wrong.

Find the particular solution for the following differential given that it passes through (-1, -6).

f ' (x) = 24x^2 - 4x + 5

I can do it well without the negative number and my answer results in: y = 8x^3 - 2x^2 + 5x + 9

Thanks...
