find the average rate of change of the function y=f(x)=1/(x-1)^2-8 with respect to x on the interval -2≤x≤0. Repeat for y=g(x)=1/(x-1)^2+5. Note that the graph of g(x) is vertically shifted from the graph of f(x). What is the vertical shift, and how does the fact that one graph is vertically shifted relative to the other explain the similarity of your two results? step by step. ​
