1. The problem statement, all variables and given/known data y=(5-x2)sqrt(x) 2. Relevant equations 3. The attempt at a solution I got as far as (5-x2)(1/2)(x)^-1/2 + (x)^1/2 (-x)(-2x) Im using the chain rule here I believe but im a tad lost as where to go from here, if ive even done it correctly up to this point. Any help would be greatly appreciated. Thanks!
