Oh boy, here we go again 
First we must convert  1 2/3 to an improper fraction.  By doing this, we get 5/3  (3/3 + 2/3)
So now we have 273 /  5/3
To divide this easier we can do something that when I learned it was called (keep, change, flip)  which basically means keep the first fraction, change the sign from division to multiplication, and flip the second fraction
This now turns into:  273/1 * 3/5 
Combine 273 and 3/5
273⋅3/5
Multiply 273
by 3
819/5
is your answer

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.
