Explain the difference between the average rate of change of y as x changes from a to b, and the instantaneous rate of change of y at x = a. Choose the correct answer below. ○ A. f(b) -f(a) b-a where y = f(x). The instantaneous rate of change of y at x= a can be found by using the formula The average rate of change of y as x changes from a to b is found by taking the limit as b approaches a of the stated formula. О в. The average rate of change of y as x changes from a to b can be found using the formula f(b)+f(a) b+a where y = f(x). The instantaneous rate of change of y at x= a is found by taking the limit as b approaches a of the stated formula. ○ C. The average rate of change of y as x changes from a to b can be found by using the formula where y = f(x). The instantaneous rate of change of y at x=a is found by taking the limit as b approaches a of the stated formula. f(b)-f(a) b-a O D. The instantaneous rate of change of y at x= a can be found using the formula where y = f(x). The average rate of change of y as x changes from a to b is found by taking the limit as b approaches a of the stated formula. f(b)+f(a) b+a
