Let f(x) represent the total number of items a subject has memorized r hours after being presented with a long list of items to learn. Psychologists refer to the graph of y = f(x) as a learning curve and to f'(x) as the learning rate. Suppose that the learning rate is 10. 1.2 f(r) = -0.06r2+ +1 a. Find an equation for the learning curve with nothing memorized at the beginning. 1 of
