Question

Which of the equations below could be the equation of this parabola?

Answer 1

Answer:

B

Step-by-step explanation:

• Parabola that is opening upward has the form  $y=ax^2$
• Parabola opening downward has the form  $y=-ax^2$
• Parabola opening leftward has the form  $x=-ay^2$
• Parabola opening rightward has the form  $x=ay^2$

Where a is a constant

Now, looking at the graph given, it takes the form  $x=-ay^2$

Where a is 3 (matching the answer).

Hence, B is the correct answer choice.
