Consider the function f(x) = 2x³-6x² - 48x +5 on the interval [-5, 7]. Find the average or mean slope of the function on this interval.
By the Mean Value Theorem, we know there exists at least one c in the open interval (-5, 7) such thatf'(c) is equal to this mean slope. Find all values of c that work and list them (separated by commas) in
the box below. If there are no values of c that work, enter None.
