dy/dx is increasing for the range 20 - 120 (and possibly beyond though not necessarily)Point of inflection at x=70 for ddy/ddx, goes from negative to positive.f(x)=.015 when x=20;f(x)=.35 when x=120

Consider the function f(x)=2x3−12x2−30x+1 on the interval [−4,7]. Find the average or mean slope of the function on this interval.  By the Mean Value Theorem, we know there exists a c in the open... more
