Answer:
The x-intercept would be located on x value "-2".
Explanation:
The x-intercept of a function is the point where said function touches the "x" axis. This always happens when there's a point with a "y" value of 0, no exceptions. So, if we're given a vertex located on (-2,0), 0 would be our "y" value, therefore this vertex is also the x-intercept of the function.
