The number of viruses (V, measured in trillions or 1012) that infect a person is a function of the degree of immunosuppression (I, the fraction of the immune system that is turned off by stress) according to V(I) = 5I2. The fever (F, measured in °C) associated with an infection is a function of the number of viruses according to F(V) = 37 + 0.4V. Find fever as a function of immunosuppression. How high will the fever be if immunosuppression is complete (I = 1)?
The above series of functional compositions describe connections between several measurements.
