![**Problem 3**: Suppose the concentration of a drug, in milligrams, present in the body can be represented by the function \( A(t) = 280(0.86)^t \) where \( t \) is in minutes since the drug has been administered. Find and interpret \( A(2) \) and \( A'(2) \), and include units. Use this information to approximate \( A(4) \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff1ac4a5c-5c91-4743-9545-fc03c7695e62%2F62cc62fc-7383-4566-af62-23a1d9c3a327%2F0fj53f_processed.jpeg&w=3840&q=75)
