a. the parabola opens down, the vertex is the maximum value
c. the parabola opens up, the vertex is the maximum value
b. the parabola opens down, the vertex is the minimum value
d. the parabola opens up, the vertex is the minimum value

the upper quartile is 15.5

school b:

minimum value is 9

maximum value is 20

the lower quartile is 12
