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.
