Homework Equations
Ok, i tried by taking the derivative of the top equation, since it includes 2, but I got the answer to be 10.
The Attempt at a Solution
By book says the answer is undefined, but I don't understand why. Thsi is under "quick review" so I'm thinking I'm making it a lot harder than it should be. Am I missing something? Why is it undefined? I keep getting 10.
