What is the derivative of (2x + 1)3 equal to?


2

2(2x + 1)2

3(2x + 1)2

6(2x + 1)2

 6(2x + 1)3 


Yanıt Açıklaması:

The Chain Rule: The derivative of composite function f (g(x)) is f'(g(x)) * g' (x). For this question our g(x) = 2x+1. The derivative of (2x + 1)3 yields to 3(2x + 1)2 * 2 which is equal to 6(2x + 1)2 . The answer is D.
