Identify whether the claim is accurate or not. If it's accurate, describe why. If it's untrue, explain why or provide an illustration that refutes it. Derivatives exist for all continuous functions.
For the following sets of variables, find all the relevant second derivatives. In all cases, first find general expressions for the second derivatives and then substitute variables at the last step.
