1. The problem statement, all variables and given/known data Find the approximate percentage changes in the given function y = f(x) that will result from an increase of 2% y = x2 2. Relevant equations 3. The attempt at a solution dy/dt = dx/dt * d/dx * x2 dy/dt = dx/dt * 2x dy/dt = 2/100 * 2x dy/dt = 4x% ? I don't know if I did this right but apparently in the back of the book I'm not suppose to have the x in there, why not?
