I think I've got 5 ok, need help with 6 and 7

5. Consider the function f (x) = 2x2 Use a spreadsheet to find the average rate of change from (include relevant information from spreadsheet with your answer): x-3 to X-10 x =3 to X - 8 X = 3 x=3 X =3 to X = 3.8 V=3 to X = 3.6 X=3 to X = 3.4 x =3 to X= 3.2 x =3 to X - 3.1 X = 3 to X = 3.01 6. Using the definition Slope T = lim f (x + 4x) -f(x) Ax To find the instantaneous rate of change at x = 3 for the function from the previous problem T. In your own words, explain how the previous two questions relate to each other
