Answer:
B
Step-by-step explanation:
- Parabola that is opening upward has the form [tex]y=ax^2[/tex]
- Parabola opening downward has the form [tex]y=-ax^2[/tex]
- Parabola opening leftward has the form [tex]x=-ay^2[/tex]
- Parabola opening rightward has the form [tex]x=ay^2[/tex]
Where a is a constant
Now, looking at the graph given, it takes the form [tex]x=-ay^2[/tex]
Where a is 3 (matching the answer).
Hence, B is the correct answer choice.
