Perfect Complements - Is min the same as max?

I have a questions that says
"The utility function is U(x.y) = max{x,2y}...."
Would I solve for the indifference curve as if it read "U(x,y) = min{x,2y}"? If not, what is the difference between the two when solving?

I know that if I were looking for the minimum, then it would have an L shaped curve. Would the indifference curve be rotated 180 degrees for maximum?
