Question 3 Consider the function f(x) = 4 - 4x on the interval [ - 3, 6]. Find the average or mean slope of the function on this interval, i.e. f (6) - f( - 3) 6 - ( -3) By the Mean Value Theorem, we know there exists a c in the open interval ( - 3, 6) such that f' (c) is equal to this mean slope. For this problem, there is only one c that works. Find it
