What is the formula for that parabola in the form of f(x)=

To find the formula for a parabola in the form of \( f(x) = ax^2 + bx + c \), you need specific information, such as:

1. The vertex of the parabola.
2. The coordinates of points through which the parabola passes.
3. Whether the parabola opens upwards or downwards.

If you provide details like:
- The vertex \((h, k)\) and another point,
- Three points on the parabola, or
- The axis of symmetry and other key points,

I can derive the formula for you.

Would you like to share such details, or clarify the context of the parabola?

1. What does the vertex form of a parabola, \( f(x) = a(x-h)^2 + k \), signify?
2. How does changing \( a \), \( b \), or \( c \) in the standard form impact the graph?
3. Can you explain how to derive the vertex from the equation \( f(x) = ax^2 + bx + c \)?
4. How do you determine if a parabola opens upwards or downwards?
5. What is the geometric significance of the focus and directrix of a parabola?

### Tip:
When working with a parabola, always check if the equation or provided points align with the axis of symmetry for quicker calculations.
