(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

f(x)= {x^3 - 2x, x<=2

x + 2, x> 2

find f'(2)

2. Relevant equations

Ok, i tried by taking the derivative of the top equation, since it includes 2, but I got the answer to be 10.

3. The attempt at a solution

By book says the answer is undefined, but I dont 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.
