The graph of a quadratic function is shown.

Which statement appears to be true?
The function has 3 zeros.
The maximum value of the function is 3.
The vertex of the graph of the function is (4, 1).
• The equation of the axis of symmetry of the graph of the function is x=1.

The statement that appears to be true is:

The vertex of the graph of the function is (4, 1).

This is because the vertex of a quadratic function is the maximum or minimum point of the parabola, and from the graph, it appears that the vertex is at the point (4, 1).
