The vertex of the parabola is .

Step-by-step explanation:

In this case, the vertex of the parabola is the absolute maximum of the graph, that is, the point .  Mathematically speaking, the vertex of the parabola is represents the only point of the range () which is related to an only value of the domain ().

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
