Question

Please help! exercise 3 is stretches and compressions in algebra 2

Answer 1

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}`
