Marcel says there is only one vertex that will yield a maximum for any given function. tomas says that if the numbers are correct, there could be two vertices that yield the same maximum. tomas is correct. there are functions in which the coordinates of more than one vertex will yield the same value for the function.

The correct answer for this question is "TRUE."
