$\"\"$

The function is $\"\"$ .

Solve the test item.

The negative coefficient of the $\"\"$ represents that the function the reflection across $\"\"$ -axis.

The parabola opens downwards.

The graph of $\"\"$ stretches the graph of $\"\"$ vertically.

The graph of $\"\"$ represents a translation up or down of the parent graph.

The value of $\"\"$ is $\"\"$ and $\"\"$ , the translation is down.

Therefore, the graph is reflected across $\"\"$ -axis, stretched vertically and shifted down by $\"\"$ units.

Graph:

Graph the fucnctions is $\"\"$ .

$\"\"$

The graph (F) matches to the above specifications.

Therefore, the function matches with the graph (F).

$\"\"$

The correct match is (F).
