A company has developed two functions, L( t) and M( t), that determine the least amount and most
C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3


amount, respectively, of revenue it will make in any given month in dollars (with t = 1 corresponding to
C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3


January).
C3



What can the company reasonably conclude if L(2) = 3,000 and M(2) =
C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3


5,000?
C3




YOUR CORRECT
ANSWER ANSWER



In February, it will make
C3 C3 C3 C3




C3 $2,000.
In February, it will make between $3,000 and
C3 C3 C3 C3 C3 C3 C3




C3 $5,000.
It will make more money in February if it uses M( t) instead of L( t).
C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3 C3




It cannot make more than $3,000 in February but can make up to $5,000 after
