Which function could be represented by the graph on the coordinate plane?

Step-by-step explanation:

we know that

The equation of a vertical parabola into vertex form is equal to

where (h,k) is the vertex of the parabola

The axis of symmetry is equal to

In this problem the parabola open upward

so

the coefficient a is positive

The coordinates of the vertex will be (the y-coordinate is negative)

so

the equation will be of the form

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

step-by-step explanation:
