Part 2 of 2 a. Around the point (1,0), is f(x,y) =x"(y+ 1) more sensitive to changes in x or to changes in y? Give reasons for your answer. b. What ratio of dx to dy will make of equal zero at (1,0)? a. Around the point (1,0), is f(x,y) = x"(y + 1) more sensitive to changes in x or to changes in y? Give reasons for your answer. O A. It is more sensitive to changes in x because the partial derivative of f with respect to x is smaller at that point. O B. It is more sensitive to changes in y because the partial derivative of f with respect to y is larger at that point. &C. It is more sensitive to changes in x because the partial derivative of f with respect to x is larger at that point. O D. It is more sensitive to changes in y because the partial derivative of f with respect to y is smaller at that point. b. What ratio of dx to dy will make df equal zero at (1,0)? dx dy (Type an integer or a simplified fraction.)
