f R denotes the reaction of the body to some stimulus of strength x, the \ sensitivity S is defined to be the rate of change of the reaction with respect to x. A particular example is that when the brightness x of a light source is increased, the eye reacts by decreasing the area RR of the pupil. The experimental formula R=37+21x4/1+0.3x4 can be used to model the dependence of R on x when R is measured in square millimeters and x is measured in appropriate units of brightness.

Question
If R denotes the reaction of the body to some stimulus of strength x, the \ sensitivity S is defined to be the rate of change of the reaction with respect to x. A particular example is that when the brightness x of a light source is increased, the eye reacts by decreasing the area RR of the pupil. The experimental formula
R=37+21x4/1+0.3x4
can be used to model the dependence of R on x when R is measured in square millimeters and x is measured in appropriate units of brightness.
Find the sensitivity corresponding to x=2x=2.
Sensitivity = ?
