Answer:
-13
Step-by-step explanation:
It gives you a few values. The values of f(t) and g(t) when time t=3, and
the values of the rates of change (first derivative) for both at the same time t=3.
f(3) = 8 unit
f ' (3) = 2 unit/s
g(3) = 3 unit
g ' (3) = 8 unit/s
--and also a value of the ratio of the two functions at t=3
