- Show that the function has partial derivative at the point (0,0) but is discontinuous at this point.The second derivative test fails when f" is zero or does not exist at the critical number of the first derivative and thus we use the 1st derivative test to determine local extrema. True or False?How do I know where they are occurring at x?
