Best ResponseYou've already chosen the best response.0Yeah 1st derivative test to find the vertex. very smart....not. I don't think a question like this would require such thing.

Best ResponseYou've already chosen the best response.0All you need for this question is finding the axis of symmetry and then subbing that value into the equation to find y.
