Question: Justify whether x + y2 = 3xy has a horizontal tangent at (2, 4). No, because 3y-3x/2y-3x?0 at (2,4)Yes, because 3y-3x/2y-3x=0 at (2,4)Yes, because 3y-3x/2y-3x=0

Justify whether x³ + y2 = 3xy has a horizontal tangent

Justify whether x³ + y2 = 3xy has a horizontal tangent at (2, 4). No, because 3y-3x²/2y-3x?0 at (2,4)Yes, because 3y-3x²/2y-3x=0 at (2,4)Yes, because 3y-3x²/2y-3x=0 at (2,4)No, because 3y-3x²/2y-3x?0 at (2,4)
