I am prepared to bet that, since there is no proof this year, they will instead have a question where they will have you verify the Mean Value Theorem.  Here are some tips and examples:

• Click the link below for the procedure to follow to "verify" the Mean Value Theorem:

• Here is an example of the type of problem I expect:
  Verify the Mean Value Theorem #1
• Here is an another example of the type of problem I expect:
  Verify the Mean Value Theorem #2
