(1 point) Consider the function 113:) : i on the interval [1, 12]. (A) Find the average or mean slope of the function on this interval. Average Slope = (B) By the Mean Value Theorem, we know there exists a c in the open interval (1, 12) such that f'(c) is equal to this mean slope. Find all values of c that work and list them (separated by commas) in the box below. List of values
