**Algebra II repost- please check**

I posted these a little while ago but this time I have answered them. 1. Does the graph of y = x – 3x2 + 5 have a maximum or minimum? 2. What is the vertex of the graph of y = -2(x - 3)2 + 4? 3. Does the graph of y = -2(x - 3)2+ 4 open up or down? My answers: 1. I cannot ...
