![### Exploring Quadratic Functions
**Consider the function:**
\[ g(x) = 2x^2 - 8x + 2 \]
1. **What is the vertex of \( g \)?**
- The vertex of the function is \((2, -6)\).
2. **What is the equation of the line of symmetry of \( g \)?**
- The line of symmetry is given by \( x = 2 \).
3. **Does \( g \) have a minimum or maximum value? What is it?**
- \( g \) has a minimum value of \(-6\).
4. **Identify the \( x \)-intercept(s) of \( g \).**
- To be determined.
5. **Identify the \( y \)-intercept of \( g \).**
- The \( y \)-intercept of \( g \) is \((0, 2)\).
**Graph of \( g(x) \):**
There is a graph presented alongside which plots the quadratic function \( g(x) = 2x^2 - 8x + 2 \). The following details can be observed from the graph:
- The graph is a parabola that opens upwards, indicating a minimum point.
- The vertex of the parabola, which is the minimum point, is located at \( (2, -6) \).
- The line of symmetry of the parabola is a vertical line that passes through the vertex at \( x = 2 \).
**Additional features of the graph:**
- The red points on the graph indicate significant points such as the vertex and intercepts.
- The grid helps in interpreting values on the graph accurately, with the x-axis and y-axis marked at intervals.
**Clear and Draw Options:**
At the bottom of the graph interface, there are various options to clear the graph and draw different types of lines and curves:
- Clear All: Removes all drawings from the graph.
- Draw: Includes tools to draw lines, curves, and points for better analysis and visualization.
