If a parabola has two x-intercepts, it means that it opens either upwards or downwards and crosses the x-axis at two distinct points.
-
If the parabola opens upwards, the vertex will be the minimum point of the parabola and will be located above the x-axis. Therefore, in this case, the vertex could be above or right at the axis but will definitely be somewhere in between.
-
If the parabola opens downwards, the vertex will be the maximum point, and it will be located below the x-axis. However, it will still be between the two x-intercepts on the horizontal axis.
Thus, regardless of whether the parabola opens upwards or downwards, the vertex is always somewhere in between the x-intercepts.
Therefore, the correct answer is:
is somewhere in between the x-intercepts.
