  11) Use the definition of the derivative to show that f '(0) does not exist where f (x) = x. Using 0 in the definition, we have lim h →0 0 + h − 0 h = lim h 0 h h which does not exist because the left-handed and right-handed limits are different.

  So the second derivative of g(x) at x = 1 is g00(1) = 6¢1¡18 = 6¡18 = ¡12; and the second derivative of g(x) at x = 5 is g00(5) = 6 ¢5¡18 = 30¡18 = 12: Therefore the second derivative test tells us that g(x) has a local maximum at x = 1 and a local minimum at x = 5. Inflection Points Finally, we want to discuss inflection points in the context of the second derivative.

  DERIVATIVES USING THE DEFINITION Doing derivatives can be daunting at times, however, they all follow a general rule and can be pretty easy to get the hang of. Let’s try an example: !Find the derivative of !!=!, and then find what the derivative is as x approaches 0. The first thing we must do is identify the definition of derivative.

From the tangent de nition of the derivative, we can see the following relationship between the shape of the graph of y = f(x) and the derivative function f0(x): If the graph of y = f (x) is smooth at and increasing, then 0) is positive. If the graph of y = f(x) is smooth at x and decreasing, then f0(x) is negative.

  The Derivative: The derivative of a function f at a point (x, f(x)) is the instantaneous rate of change. The derivative is the slope of the tangent line to the graph of f at the point (x, f(x)). The derivative is the slope of the curve f(x) at the point (x, f(x)). A function is called differentiable at (x, f(x)) if its derivative exists at (x ...

  there is a derivative, and hence there is a new function that assigns to each such nice point x in the domain of f a value, f0(x). Not sur-prisingly, we call this new function the derivative of f(x). Thus, The derivative of a function y = f(x) is the function defined by f0(x) = lim h→0 f(x+h)−f(x) h.
