In high school and college, students’ study and memorize large volumes of information. The law of Exercise tells us that more we use the information, the longer we retain it, and vice versa. Consequently information learned during this period are often or not forgotten. Neuroscientists were able to come up with the function f(x) = 80e¬0.5× + 20 which describes the percentage of information, f(x), that a particular person remembers x weeks after learning the information. A. How many weeks will a person retain about 40 percent of the information?
