Explain why the function is differentiable at the given point. f(x,y)=x3y2,(−2,2) The partial derivatives are fx(x,y)= and fy(x,y)= , so fx(−2,2)= and fy(−2,2)= . Both fx and fy are continuous functions, so f is differentiable at (−2,2). Find the linearization L(x,y) of the function at (−2,2). L(x,y)=12n−8y+16
