ANSWER

EXPLANATION

The given parabola has equation;

Comparing this equation to

we have

a=34, b=-6 and c=15

The x-coordinate of the vertex is given by:

The y-coordinates of the vertex is obtained by substituting the x-value of the vertex into the equation:

The vertex is

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
