CAN SOMEONE PLEASE HELP ME? 13. Problem of the Matthew chapter determines that the braking distance, in meters, from a moving car at about 100 km / h corresponds roughly at d = -2.8 t - 5)^2+ 70, where t is the time elapsed, in seconds.

a) Determine the reciprocal of this function. What does it represent in the context of the question?

b) In this context, what should be the domain and image of function and its reciprocal?

c) Compare the distance traveled during each of the first three intervals 20 s from the start of braking.
