Ok so I take it d shifts the curve off the origin, so if it is going through the origin, there is no d value?
And how many points would I need to come up with a, b, and c values?
Hello,
I am trying to find the equation in the form ax^3+bx^2+cx+d for the curve passing through the origin and (40 sq root 6, -20).
How do I find the a, b, c, and d values?
