### Understanding Quadratic Functions: Parabolic Graph Analysis In this educational module, we will delve deep into quadratic functions and their graphical representations. Specifically, we will focus on the parabolic graph which is a fundamental concept in algebra and calculus. #### Parabolic Graph Analysis The image above showcases a parabola, which is the graphical representation of a quadratic function. Here's a detailed breakdown of the graph for educational purposes: 1. **Graph Description**: - **Axes**: The graph features two perpendicular axes: the horizontal axis (x-axis) and the vertical axis (y-axis). - **Parabola Orientation**: This parabola opens upwards, indicating that the quadratic function has a positive leading coefficient. 2. **Vertex**: - The vertex of the parabola appears to be at the point (0, 2). The vertex is the minimum point on the graph of a parabola that opens upwards. 3. **Intersection with y-axis**: - The parabola intersects the y-axis at y = 2, which is also the vertex in this particular graph. 4. **Shape and Symmetry**: - The parabola is symmetrical about the vertical line passing through its vertex, which in this case is the y-axis (x = 0). 5. **Shaded Region**: - The area under the curve of the parabola is shaded, indicating the region for which the quadratic function yields values less than or equal to the function's value at the vertex. 6. **Scale**: - The horizontal axis (x-axis) is scaled from -3 to +4. - The vertical axis (y-axis) is scaled from -1 to +7. #### Key Insights: - **Equation Form**: The standard form of the equation of a parabola is \( y = ax^2 + bx + c \). In this case, the quadratic function is of the form \( y = x^2 + 2 \), suggested by the vertex at (0, 2) and the symmetry of the graph. - **Vertex Form**: Another way to express the equation of a parabola is the vertex form, \( y = a(x-h)^2 + k \). Here, \( h = 0 \) and \( k = 2 \), corresponding to the vertex coordinates (0, 2). - **Applications**: Understanding the shape and properties of parabolas is crucial in
