Answer:
middle graph
Step-by-step explanation:
Soluton
The  second (middle ) graph is the only one that works.
- First of all when you simplicity the right, you get y = x^2 - 1). That means that x does not go through 0,0. If you put x = 0 into x^ -  1 = 0, you get - 1. So on that basis alone both the first and third graphs are incorrect.
- Second, both xs in the factors are plus, so x^2 is plus, which means the graph opens upward.

Answer:
   2 1/4 days
Step-by-step explanation:
You could extend your table a bit to help answer this.
   (days, hours)
   (1, 24)
   (1/2, 12)
   (1/4, 6)
   (2, 48)
Now, we observe that 54 hours is 6 more hours than 48 hours, so will be 1/4 day more than 2 days.
54 hours is 2 1/4 days
