I only have the explanation for linear homogeneous ones. I don't know how to do these:

Give a recursive form (including bases) for the following functions:

a. f(n) = 2 + (-1)^n

b. f(n) = n(n+1)

c. f(n) = 2n - 2

d. f(n) = n^2 – n

e. f(n) = 3^n + n⋅3^n

If someone could explain one or two it would help alot.

Thanks
