Given a negative x value, find the corresponding y value for curves in the form y = x² + c Tom and Katie are discussing the table of values for \( y=x^{2}-1 \) \begin{tabular}{|l|l|}
\hline\( x \) & \( \bigstar \) \\
\hline\( y \) & \( 15 \) \\
\hline
\end{tabular} Tom says the star could be \( 4 \)

Katie says the star could be \( -4 \)
