Problem 6. (1 point) Considerthe function f(ar;) : 2:1;3 7 9:32 7 243; + 10 on the interval [76, 8]. Find the average or mean slope of the function on this interval. Average slope: By the Mean Value Theorem, we know there exists at least one value c in the open interval (76, 8) such that f' (c) is equal to this mean slope. List all values c that work. If there are none, enter none . Values of c: Note: You can earn partial credit on this problem. preview answers
