Arrange the parabolas with respect to the position of their vertices from left to right. y=f(0)
y=f(1-4)
y = f(x+3)
y=f(x-7)
y=f(x+2)
y=f(1-1)

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
