l Find the average rate at change fer the given function. I x}=x2+2xbetweenx=andx=i' _ 1ill-"hat formula is used to cc-mpute the average rate of change over any time interval? Cheese the correct answer helaw. {j A. The average rate of change ever any time interval, as it: changes from El tn 1", is equal to T E]. {j E, The average rate of change ever any time interval, as it changes from El tn 1", is equal to f'} f{El]. rmrrn} rn ' T i] {in} D. The average rate of change ever any time interval, as it: changes from El ten 1", is equal to W. C} C. The average rate of change ever any time interval, as it changes from El tn 1", is equal to Find f' (x) for the following function. Then find f' (2), f'(0), and f'( - 6). f(x) = - 3x +5 f'(x) = (Simplify your answer.)
