Answer:
C
Step-by-step explanation:
average rate of change is just the rate at which the graph goes up or down over the interval thats given. here, we're just looking at between when x=0 and x=2. however, the graph goes down more between 0 and 1 than it does between 1 and 2, which is why we're looking for the average. the graph goes down 4 in total. divide this change by 2 to get the average which is -2
