The graph above is the graph of y=x2y=x2 translated and reflected in the xyxy-plane. Find an equation for this graph.

 

Please help. The answer I got was 1-(x-2)^2+-7 but I'm sure it might be incorrect

The graph above is the graph of \(y=x^2\) translated and reflected in the xy-plane.
Find an equation for this graph.

 

1. translated

\(\begin{array}{|rcll|} \hline y_0 &=& x_0^2 \\ && \boxed{y = y_0+2\\ x=x_0+7 } \\ (y-2) &=& (x-7)^2 \\ y &=& 2 + (x-7)^2 \quad \text{ after translation} \\ \hline \end{array}\)

 

2. reflected

\(\begin{array}{|rcll|} \hline y_0 &=& 2 + (x_0-7)^2 \\ && \boxed{y = -y_0\\ x=x_0 } \\ -y &=& 2+(x-7)^2 \\ \mathbf{y} &=& \mathbf{-2-(x-7)^2} \quad \text{ after translation and reflextion} \\ \hline \end{array}\)
