At the end of 1993, scientists tracked 1550 nonfunctional components in orbit and projected 42 such objects are added each year. Suppose that an average of 15 of these are brought back to Earth each year.
Question.
Let t represent time in years. Write the function D that models the total number of cataloged nonfunctional components in orbit at the end of the year if 42 such objects are added each year to the initial 1550 objects in orbit.
