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 down.

Therefore, the graph is compressed vertically and shifted down by units.

Graph:

Graph the fucnctions is .

The graph (C) matches to the above specifications. \ \

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

The correct match is (C).
