Please answer :') Which of the following parabolas has an axis of symmetry at x=1?

y=(x+5)2−1

y=(x−1)2+5

y=(x−5)2+1

y=(x+1)2+5

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 .
