differentiate term by term
using the general form
if f\9) = ax^n then f'(x) = anx^(n-1)

Great, quick answers. Thanks. Could I use the definition and determine it by doing [2(x+h)^3+ 12(x+h)^2 ... etc.? And the power series method is just easier? Or is the definition not appropriate in this context?

you could use the definition but the power method is valid here
