If (dy)/(dx)=2x+2y then (d^2y)/(dx^2)= 2x+2y+2 4x+4y+4 2x+2y 4x+4y+2

To find the second derivative , we need to differentiate the given derivative with respect to .Differentiating with respect to , we get: Substituting the given derivative into the equation, we get: Therefore, the correct answer is .
