Plzz he The graph of a quadratic function passes through (3,2), (4,7), and (9,2). Does the graph open up or down? Identify the correct answer with the best explanation.

up; The point (4,7) is above (3,2) and (9,2) and is within the part of the domain that is between these two points. So, the graph opens up.

down; The point (4,7) is above (3,2) and (9,2), which are at the same height. So, (4,7) must be the vertex and the graph opens down.

up; As the x-coordinates increase from 3 to 4 to 9, the y-coordinates go from 2 up to 7 then back to 2, which shows that the graph curves up.

down; The point (4,7) is above (3,2) and (9,2) and is within the part of the domain that is between these two points. So, the vertex is above these points and the graph opens down.

up; The x-coordinates increase from 3 to 4 to 9, indicating that the graph curves up.
