The figure above shows the graph of y=a(x+b)(x+c), where a, b, and c are constants and |c|>|b|. Which of the following must be true?

  1. a>0
  2. c>b
  3. bc<0

but b must be positive if it falls less than the origin and c must be negative because when y is zero one of the factors must result in zero, the C is the greaater distance from the origin since and because it is above zero it must be positive to make that factor result in 0

I see that the value of x for b is less than zero so it is ( x+1) lets say, and then the value of x for c must be positive so ( x-6) lets say . I dont see where X =-c for that factor? I see x = +c
