Algebra 2 unit 2 question. connexus.

Which equation is most likely represented by the graph above??

 The correct answer is the first option: y=(2x-1)(2x-3)(2x+5)

 Because: if you give values to the variable "x" and graphic each point calculated, you will obtain the graph above. For example:

If x=-3/2:

 y=(2x-1)(2x-3)(2x+5)
 y=(2(-3/2)-1)(2(-3/2)-3)(2(-3/2)+5)
 y=48 (As you can see in the graph)

 If x=0:

 y=(2x-1)(2x-3)(2x+5)
 y=(2(1)-1)(2(1)-3)(2(1)+5)
 y=15 (It is shown in the graph)

 If x=1:

 y=(2x-1)(2x-3)(2x+5)
 y=(2(1)-1)(2(1)-3)(2(1)+5)
 y=-7  (As you can see the graph attached)
