Suppose the following about a certain object:

I. The object's altitude is a function of time, represented by the function A(x) where here x is time.

II. The temperature of the object is a function of its velocity, represented by the function T(x), where here x is the object's velocity.

III. The weight of the object is a function of its altitude, represented by the function W(x), where here x is the object's altitude.

IV. The velocity of the object is a function of its weight, represented by the function V(x), where here x is the object's weight.

The function F(t) which gives us the object's temperature at time t can be represented as
