Substitute 0 for \( x \) and, without using a calculator, find the percentage of information remembered at the moment it is first leamed. b. Substitute 1 for \( x \) and find the percentage of information that is remembered after 1 week. c. Find the percentage of information that is remembered after 4 weeks. d. Find the percentage of information that is remembered after one year ( 52 weeks). a. At the moment it is first learned, \( \square \% \) of the information is remembered.
