Consider the function f(x) = 4+8 on the interval [2,7]. (A) Find the average or mean slope of the function on this interval. Average Slope 47-42 (B) By the Mean Value Theorem, we know there exists at least one c in the open interval (2,7) such that f'(c) is equal to this mean slope. Find all values of that work and list them (separated by commas) in the box below. List of values: 9+2/14 2
