A flow has a velocity field defined by V={(?2x2?2y2)i+(?4xy)j}, where x and y are in feet. Determine the equation for the equipotential line passing through point (3 ft, 2 ft). Express your answer in the form y2=f(x). If the potential function does not exist, answer "rotational."

Express your answer in terms of x.
