Answer
The graph for equation $x={{y}^{2}}-1$.
Work Step by Step
$x={{y}^{2}}-1$ (equation -1)
$\begin{align}
& y=-\frac{b}{2a} \\
& =-\frac{\left( 0 \right)}{2\cdot \left( 1 \right)} \\
& =0
\end{align}$
Now for the x value put $y=0$ in equation (1).
$\begin{align}
& x={{\left( 0 \right)}^{2}}-1 \\
& =-1
\end{align}$
The vertex is$\left( -1,0 \right)$.
Now choose some value of x on both sides of the vertex and compute the corresponding y value
$\begin{matrix}
x & y \\
0 & 1 \\
3 & 2 \\
0 & -1 \\
-2 & 3 \\
-1 & 0 \\
\end{matrix}$
