## Problem 6:

**Using the Quadratic function with the given vertex and extra data point.**

### Graph Details:
- The graph shows a parabola representing the function \( y = f(x) \).
- The vertex of the parabola is located at \((-3, 9)\).
- Another specified point on the parabola is \((6, -9)\).
- The graph is symmetrical about a vertical line, which passes through the vertex.

### Questions:

**(a)** What is the axis of symmetry?

**(b)** Find a model for the quadratic function in vertex form: \( f(x) = a(x - h)^2 + k \) (you will need to find \( a \) using the extra data point).

**(c)** Based on your quadratic function, find \( x \) where \( f(x) = -5 \). (Show this algebraically and state results to two decimal places).
