Crawford concluded that the area of the pupil in square millimeters is -0.4 160x +94.8 f(x) -0.4 4x + 15.8 of light are entering the eye per unit time {0x37} = when x units When 3 units of light are entering the eye per unit time, what is the rate of change of pupil size with respect to a unit change in light intensity? (be sure to round to two decimal places and do not add units yet)
