Solution:

Given:


y=-7(x+9)^2

The parent function is;


y=x^2

The following transformations take place from the parent function.


\begin{gathered} y=(x+9)^2 \\ Shifts\text{ left 9 units} \end{gathered}


\begin{gathered} y=7(x+9)^2 \\ Vertically\text{ stretches by a factor of 7} \end{gathered}


\begin{gathered} y=-7(x+9)^2 \\ Reflects\text{ over the x-axis} \end{gathered}
