Problem 3: Finding the Derivative for x / 4 (22 points) To find the derivative for multiple points at once, we will evaluate the derivative at a constant (but unknown) value a. By considering the cases a 4 separately, we will cover all values for a except a = 4. Remember that we have two different definitions for the derivative! Both definitions can be used for any derivative, but sometimes one definition is easier to use for a particular derivative. In the following problem, we will use different definitions for when a 4. While you are working on the following problem, ask yourself why you would use one definition over the other. a) (2 points) For a
