Question

How do I calculate the derivative of 2x^3 + 12x^2 - 30x +10? thanks.

Answer 1

power rule:
6x^2+24x-30

Answer 2

differentiate term by term
using the general form

if f\9) = ax^n then f'(x) = anx^(n-1)

Answer 3

ax^n =a*nx^n-1

Answer 4

if f(x) i meant to write!!

Answer 5

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?

Answer 6

fine the Ybbutton witha x above it

Answer 7

the Y above* it

Answer 8

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

Answer 9

Perfect. Thanks.
