Identify the graphsA (blue), B(red) and C (green) as the graphs of a function f(:1:) and its derivatives f'(a':) and f"(:c). (Clicking on the sketch will give you a version of the picture in a separate window.) ? v is the graph of the function, f(23) . ? v is the graph of the function's rst derivative, f'(a:) . is the graph of the function's second derivative, f"(:r:) . Hint: Remember that f'(:c) is itself a function, and we can nd the derivative of the function f'(;v), which is called the second derivative of the function f(:l'2) and denoted by f"(:1:)
