Identify the vertex of the parabola
The vertex of the parabola is located at the minimum point on the graph, which is \( (1, 0) \).
Determine the interval where the function is increasing
The function increases where the graph rises from left to right. This occurs to the right of the vertex, where \( x > 1 \).
Match with the given options
The interval \( x > 1 \) is represented in inequality notation as \( 1 < x < \infty \).
