Answer:
9
Step-by-step explanation:
The reason why that is wrong is because it says in terms o pi which means you do NOT multiply pi by the radius squared.
EQUATION FOR AREA OF A CIRCLE: 
When you put it all together you get: 
which equals 
DO NOT MULTIPLY 9 AND PI. IT'S JUST 9
hope this helped :)

Well the first obvious thing is that the axis of symmetry is 0.5, so we can automatically cross out (C).
All the answers have the correct vertex, so lets find the formula for the function.
Fortunately, from my point of view, I can see two points that have their coordinates as integers, (-1, -3) and (2, 3), we can plug these into the already given "formulas" in the options (A), (B), and (D).
Out of the three choices, the formula in option (D) satisfies both coordinates, thus option (D) is correct.
