The line x=2 is the axis of symmetry for a parabola the focus of the parabola is located 3 units from the vertex which could be the equation for the parabola

See explanation

Step-by-step explanation:

Remember to always post a complete question in order to get the specific solution you are looking for.

It was that x=2 is the axis of symmetry of the required parabola:

The focus is 3 units from the vertex.

The could multiple parabolas with the given information.

Let y =3 be the directrix, then the vertex will be at (2,6).

The focus will be at (2,9).

In this case the parabola has equation:

This parabola has the features described in the question.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
