Your inequality is written in mathematically wrong form and needs to be corrected.
A correction is needed.
////////////////
From the point of view of Math, the writing and wording in this problem are mathematically ILLITERATE,
since inequalities do not define a curve.
To discuss the features of a curve, an EQUATION is needed, not inequalities.
Who is a person which created it ?
Lowest possible score to him (or to her) for his (or her) composition.
I would say, it is embarrassing to show this composition to people around.

y=>(x+1)(x-3)
Vertex occurs for the x values exactly in the middle of (-1,0) and (3,0).
That is at  .
Note that the INEQUALITY will not include the vertex for the reference parabola.
