Answer:
The x coordinate of the parabola's vertex is: 5
Explanation:
Although you didn't finish the phrases of the question, if they were asking the x-value for the x-coordinate of the parabola's vertex, which is a typical question for this type of problem, recall that the vertex is position equidistant from the parabola's branches because the parabola is a symmetric figure.
Therefore we need to find the point half way between x = 2 and x = 8.
Notice that the distance between these two points is "6" units, and half of such distance is "3" units, so the vertex must be located 3 units to the right of 2 (or equivalently 3 units to the left of 8).
Therefore, the x-coordinate of this parabola's vertex is "5"
