- The image displays a graph of the function \(y = x^2\), which is a parabola opening upwards.
- The horizontal axis represents the variable \(x\), and the vertical axis represents the variable \(y\).
- Two points are explicitly marked on the graph: point \(A\) is located at the coordinates \((1, 1)\), and point \(B\) is located at the coordinates \((4, 16)\).
- On the left side of the graph, where \(x\) values are less than 1, text indicates that "the slope is negative here," corresponding to the decreasing part of the parabola.
- On the right side of the graph, where \(x\) values are greater than 1, text indicates that "the slope is positive here," corresponding to the increasing part of the parabola.
