$\"\"$

The function is $\"\"$ .

Solve the test item.

As the $\"\"$ coefficient is positive, the parabola open upwards.

The graph of $\"\"$ compresses 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 up.

Therefore, the graph is compressed vertically and shifted up by $\"\"$ units.

Graph:

Graph the fucnctions is $\"\"$ .

$\"\"$

The graph (B) matches to the above specifications.

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

$\"\"$

The correct match is (B).
