Identify the vertex of the parabola
The graph shows a downward-opening parabola. The highest point (vertex) of this parabola is located at the coordinates \((1, 1)\).
Determine the maximum value
The maximum value of a function \(f(x)\) is the \(y\)-coordinate of its vertex. Since the vertex is at \((1, 1)\), the maximum value of the function is \(1\).
Match with the given options
The maximum value is represented by the equation \(f(x) = 1\).
