Question: Use the function to show that x (0, 0) and y (0, 0) both exist, but that is not differentiable at (0,

Use the function to show that ƒx(0, 0) and ƒy(0, 0) both exist, but that ƒ is not differentiable at (0, 0).

f(x, y) = = 5xy x + 0, (x, y) = (0, 

f(x, y) = = 5xy x + 0, (x, y) = (0, 0) (x, y) = (0, 0)
