Hey I was doing an integration question and I got the answer:

$\displaystyle {y}=6{x}-2{x}^2-{x}^3+c$ the final marking point on the question was to work out c. The point went through the origin so the end answer (which I had to look up) was $\displaystyle {y}=6{x}-2{x}^2-{x}^3$. How do I work out c if say the curve $\displaystyle {y}=6{x}-2{x}^2-{x}^3+c$ went through $\displaystyle (3,2)$?
