WEBThe average rate of change takes two points and calculates (y2 - y1)/(x2 - x1). It's not really accurate for the actual rate of change at the first point, though. So by bringing the second point closer and closer to the first point, we get closer and closer to the actual rate of change at that first point.

WEBAverage Rate of Change Formula. The average rate of change function describes the average rate at which one quantity is changing with respect to something another quantity. The average rate of change formula is given as, A(x) = [f(b) - f(a)] / (b - a) where, A(x) = Average rate of change; f(a) = Value of function f(x) at a; f(b) = Value of ...

WEBAverage Rate of Change Definition. The average rate of change of a function is given as: $$\frac{f(b)-f(a)}{b-a}$$ Where f(b) and f(a) are the values of the function f at points b and a respectively. The formula gives us the rate of increase (or decrease) the function experiences between endpoints a and b.

WEBy equals 1/8 x to the third minus x squared. Over which interval does y of x have an average rate of change of 1/2? So let's go interval by interval and calculate the average rate of change. So first let's think about this interval right over here. x is between negative 2 and 2. So negative 2 is less than x, which is less than 2.
