... f(a) )and (b, f(b)). The instantaneous rate of change of f at x = a can be approximated by the average rate of change of f on [a, a + h] for h very close to zero. As h gets closer and closer to ... rate of change over the tiny interval approaches the instantaneous rate of change at x = a. The instantaneous rate of change of f at x = a ≈ f(a +h) − f(a) (a + h) − a for h...
