The Average Rate of Change<span> function describes the average rate at which one quanity is changing with respect to something else changing. </span><span> For this case, the first thing you should do is observe the intervals for which the function decreases. Remember that the definition of average rate of change is given by: </span> <span> For AVR to be negative, it must necessarily pass: </span> <span> The interval that meets both conditions is: x = 0 to x = 2.5 Answer: x = 0 to x = 2.5 option 3</span>
