Let us see who can first answer the question... its MATH time... participate and win joy

Who can solve it first? First ten people will be called the "MATHERS" for today.... let's go go go.... heheheeh


A function f (t) depends on two variables a and b according to the equation
f (t) = a (t) e ^ b (t). At one point in time, a =3 and is decreasing at a rate of 4 units per second. At the same point in time, b=1 and is increasing at a rate of 2 units per second. If f(t) increasing or decreasing at that moment?
