TopicDifferentiation from First Principles
TypeFirst principles: polynomial (find gradient)
DifficultyModerate -0.5 This is a straightforward application of the first principles formula to a simple polynomial (2x² - 3) at a specific point. While it requires careful algebraic manipulation, it's a standard textbook exercise with no conceptual difficulty beyond applying the definition of the derivative. The simplicity of the polynomial and evaluating at a single point makes it easier than average.
Spec1.07g Differentiation from first principles: for small positive integer powers of x

  1. The quadratic polynomial \(2 x ^ { 2 } - 3\) is denoted by \(f ( x )\).
Use differentiation from first principles to determine the value of \(f ^ { \prime } ( 2 )\).
