Answer:

1001

1

Step-by-step explanation:

If a quadratic function crosses the x-axis twice, it has two solutions. For a quadratic function in ax^2+bx+c with discriminant b^2-4ac, the following is true:

  • If b^2-4ac>0, then the quadratic has two real solutions
  • If b^2-4ac=0, then the quadratic has one real solution
  • If b^2-4ac, then the quadratic has no real solutions

Therefore, in order to have two solutions, a quadratic's discriminant must be larger than 0. The only two answer choices that satisfy this are 1001 and 1.
