Can I get a help please ​
iogann1982 [59]

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.
