Part 1
For the function, s = f(t) = 2t^2, where s = f(t) is the distance of an object moving in straight line from a fixed point t seconds after the clock starts, use the difference quotient in the preceding slide to calculate the approximate instantaneous speed when t = 3 and h = 0.01.
Part 2
For the graph of the function, s = f(t) = 2t^2, where s = f(t) is the distance of an object moving in a straight line from a fixed point t seconds after the clock starts, what is the interpretation of the approximate difference quotient calculated in part on the graph of the function, s = f(t)?
