**Graphing Quadratic Functions**

**Function to Graph:**

The quadratic function given is \( g(x) = 2(x + 7)^2 + 2 \).

**Understanding the Graph:**

1. **Equation Format:**
   - The function is written in vertex form: \( g(x) = a(x-h)^2 + k \).
   - Here, \( a = 2 \), \( h = -7 \), and \( k = 2 \).

2. **Features of the Graph:**
   - **Vertex:** The vertex of the parabola is at \((-7, 2)\).
   - **Direction:** Since \( a = 2 > 0 \), the parabola opens upwards.
   - **Stretch:** The coefficient 2 indicates a vertical stretch, making it narrower than the basic parabola \( y = x^2 \).

3. **Graph Paper Setup:**
   - The graph paper is a coordinate plane with both axes ranging from -10 to 10.
   - The origin (0,0) is at the center of the grid.

4. **Interactive Tool:**
   - A "Draw" button with a parabolic shape icon indicates that users can draw the graph directly onto the grid interactively.

**Graphing Steps:**

- **Identify the Vertex:** Plot the vertex \((-7, 2)\) on the coordinate plane.
- **Symmetry:** Use the axis of symmetry, which is the line \(x = -7\), to ensure accurate plotting.
- **Additional Points:** Calculate and plot additional points on either side of the vertex for better accuracy.
- **Draw the Parabola:** Using the plotted points and symmetry, sketch the parabola opening upwards.

In this way, understanding the structure of the equation and the features of quadratic graphs can aid students in correctly graphing quadratic functions.
