Answer

Option (d)

Work Step by Step

The provided function, $x={{\left( y-2 \right)}^{2}}-5$ On comparing the above equation with $x={{\left( y-k \right)}^{2}}+h$ where $\left( h,k \right)$ is vertex, the vertex will be $\left( -5,2 \right)$. To find ordered pairs, choose values for $y$ on each side of the vertex. Then compute the values of $x$ and $y$ with the help of the given equation in below table. $\begin{matrix} x & y \\ -5 & 2 \\ -1 & 0 \\ 4 & 5 \\ 4 & -1 \\ 11 & 6 \\ \end{matrix}$ From the graph it can be found that this is the graph of parabola which has the vertex $\left( -5,2 \right)$. The graph that matches with the provided equation is the graph of option (d).
