ax^3 + bx^2+cx+d=0 is standard form
How do I find the a, b, c, and d values given only a data table
Ex:
X | Y
0 | 0
1 | 3
2 | 14
3 | 39
4 | 84
What is the equation of that? it's cubic. What's the A B C and D?
Without using a calculator.
Thanks in advance
Thank you, that works and I knew that but that's not what I was looking for I'm looking for something like this
I want to be able to look at the table and determine the A B C D without having to do an equation. For the Quadratic pattern the A is the last column cut in half, the B is the top of the 1st column after Y minus the A. The C is the Y intercept.
How do you do I find the A B C D? please explain in detail.
Thanks again.
