(4) Use the definition of derivative (not any shortcut formulas) to find the derivative of the following function: f(x) = x2 + 8x +9
Find the second-order partial derivative. Find fxy when f(x,y) = 8x®y - 7y2 + 2x. O A. 24x? B. 48xy O C. - 14 OD. -28
Consider the function G(x,y) = 2x4 + 4xy + 3y2 + 8x Find an expression for D(x,y), the function that is used to determine if a critical point is an extremum or a saddle point. You do NOT have to find any critical points, only the function D.
