A function is graphed on the coordinate plane. It is a parabola with an open circle at the vertex left-parenthesis 3 comma 0 right-parenthesis. There is a point graphed at left-parenthesis 3 comma 3 right-parenthesis that is not on the parabola.

The correct response is:

The function has a removable discontinuity at x = 3.

This is because the vertex of the parabola is at (3, 0) but is represented by an open circle, indicating that the function does not take on that value at x = 3. However, since the function approaches a limit at that point (the value of the parabola close to x = 3), it indicates a removable discontinuity. The point (3, 3) does not belong to the function, reinforcing this conclusion.
