Chapter 8, Section 8.4, Question 001 Find the partial derivatives 'x and fy of the function f(x,y). The variables are restricted to a domain on which the function is defined, f(x, y) = 4x² + 3xy + 4y + x(x, y) fy(x, y) -
Chapter 8, Section 8.4, Question 016 * Your answer is incorrect. Try again. Find all points where the partial derivatives of f(x, y) are both 0, where f(x, y) = 6x2 + 2y2 Input the points separated by ; below. For example: (-1,9); (2,3); (4,2) if there are three points, or (-1,-1) if there is only one point. The point(s) where the partial derivatives of f(x, y) are both are Q
