Question

A. Graph the following quadratic functions in the Cartesian coordinate plane. (1 point for correctly solved vertex, 2 points for a properly constructed table of values with intervals of one unit, and 2 points for a correctly graphed function.) 1. \( y=x^{2}-1 \) Solution and answer: \begin{tabular}{|l|} \hline \( \boldsymbol{x} \) \\ \hline \( \boldsymbol{y} \) \\ \hline \end{tabular} 2. \( y=-x^{2}+2 x \) Solution and answer: \begin{tabular}{|l|l|} \hline \( \boldsymbol{x} \) \\ \hline \( \boldsymbol{y} \) & \\ \hline \end{tabular}
