Now that you have had some practice with calculating the average and instantaneous rates of change, you will have an opportunity to demonstrate what you have learned by completing an assignment. Please complete the questions below, which must then be submitted to your instructor for grading. (14 marks) 1. Determine the average rate of change between the points x, = -4 and x2 = 4 in the function f(x) = x<. marks knowledge determine the average rate of change between points x and in function f consider x- instantaneous at point by choosing following values for h: application ajh="1" bj h="0.1" c comment on your results parts a to above. which value gives you best estimate why what can do get an even better communication>
