To interpret the key features of the graph of the upward opening parabola and its transformation from the parent function \(y = x^2\), the correct response would focus on the nature of the transformation.
Given that the parabola shows changes in the y-values while maintaining the same x-values (since all x-values are taken within the range given) and considering the description of a vertical stretch, the best choice among the options provided is:
This is a vertical stretch of the parent function \(y = x^2\) due to the changes in the y-coordinates of each point.
This accurately captures that the transformation is vertical (stretching vertically) and relates specifically to the y-coordinates of the plotted points.
