using advance function i just need a ii)

2- A phOtOgrapher uses a light meter to measure the intensity of light from a flash bulb. The intensity for the ash bulb, 1, measured in lux, is a function of the distance from the light, d, ,measured in metres, and can be represented by 10 [(00 = F ,a' > U a) Determine the following, to two decimal places. i) the average rate of change in the intensity of light for the interval [2, 4] \\/ / ii) the approximate instantaneous rate of change in the intensity of light at exactly 5 m from the ashbulb. {V 4 \\-'- \\{ , '| 1 3L, . i a; f?\" ,. ,3 .\\v \"W, =\\ ._7 _ '3 b) What does the Sign of your answer to part a), subpart ii), indicate about the light intensity? \\/
