Math Competition

I volunteered to grade tests for the Temple’s High School Math Competition but first I had to come up with an answer sheet.  The first question for the 9th and 10th grade test was:Equation

I have no idea how to evaluate that.  Normally I’d take a few derivatives and pray but those are geometric functions, taking their derivatives is like digging a deep hole in sand.  We’re throwing this at 9th graders?  The tests should be easy to grade as I look at blank page after blank page.  I’ll give them partial credits for “I have no fucking clue” or dirty limericks.
