The vertex of a parabola is at (12, -4), and its axis of symmetry is vertical. One of the x-intercepts is at \((18,0)\). What is the x-coordinate of the other x-intercept?

Reflect point \((18,0)\) over the axis of symmetry, which is \(x=12\).

 

After the reflection, the other x-intercept is at \(\color{brown}\boxed{(6,0)}\)
