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 same as 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 reflected across -axis, compressed vertically and shifted up
units.
Graph:
\Graph the fucnctions is .
The graph (D) matches to the above specifications.
\Therefore, the function matches the graph (D).
\The correct match is (D).
