Which is sketched at the end of this answer.
A quadratic equation has the format:
It's roots are given by:
The number of roots depends on the discriminant , that is:
- If , it has two different real roots.
- If , it has one real root.
- If , it has no real roots.
In this problem, it will have only positive y-values if: and
Thus, an example is:
