4. Example (2) Find the derivative of f(x) = 4x at any point x

5. Example (3) Find the derivative of f(x) = x 2 at any point x

6. Example (4) Find the derivative of f(x) = x 3 at any point x

7. Example (5) Find the derivative of f(x) = x 4 at any point x

8. Power Rule Let: f(x) = x n, where n is a real number other than zero Then: f'(x ) = n x n-1 If f(x) = constant, then f ' (x) = 0
