16) Consider the function f(x)=2x3−6x2−90x+5 on the interval [−6,7]. 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 (−6,7) 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. If there are no values of c that work.
