Description : Help on a difference quotient question?
Last Answer : answer:This is just another way of expressing the limit of the slope at t = 1. It is the same as looking at [(1 + h) – f(1)] /h f(1) = 1/(1 – 2) = -1 (f(t) – f(1)]/(t – 1) = [1/(t-2) + 1]/(t – 1) = [(t – 1)/(t – 2)]/(t – 1) = 1/(t – 2) The limit as t approaches 1 is -1.
