The only value in the domain where f(x) = 0 is x = 1.
According to the graph, the function f(x) = 0 at x = 1.
The graph shows a parabola that intersects the x-axis at x = 1.
A parabola is a symmetric curve, so the other point of intersection with the x-axis is also at x = 1.
Therefore, the only value in the domain where f(x) = 0 is x = 1.
