Answer
The equation $x={{y}^{2}}+3$
Work Step by Step
Consider the equation,
$x={{y}^{2}}+3$ (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).
$\begin{align}
& x={{\left( 0 \right)}^{2}}+3 \\
& x=3 \\
\end{align}$
The vertex is $\left( 3,0 \right)$.
Now choose some value of x on both sides of vertex and compute the corresponding y value.
$\begin{matrix}
x & y \\
3 & 0 \\
4 & 1 \\
7 & 2 \\
4 & -1 \\
7 & -2 \\
\end{matrix}$
