Grade 12 Advanced Functions help please!
Use the degree and the sign of the leading coefficient to determine the value of the constant finite differences.
f(x) = 4x^3 +2x^2  x +5

How do I do that? I know the degree is 3, and the sign is negative... Thanks!

I don't know what constant finite diff. Is but i think it will be 2x. I got this by dividing the first term by the second term

I think a shortcut is to multiply the leading coefficient by twice the degree.

It works for this example and another that I tried, but it might not work in all cases.

Thanks ~ I haven't taken calculus yet so I just had to make really long tables for all of my questions. I got the right answers tho! :)
