### Calculus and Parabolas: Analyzing Graphs and Functions #### Overview This article explains how different transformations of functions and their derivatives appear graphically, using both visual and mathematical methods. We will analyze multiple graphs showing these functions and derivatives, and explain the transitions between them. #### Detailed Explanation of Graphs 1. **Graph 1 (Top Left) - Function: \( y = f(x) \)** - **Description**: This graph represents the original function \( f(x) \). The curve (in red) follows a parabolic shape, starting high, dipping downwards to form a 'U' shape, and then rising again. - **Key Features**: - **Vertex**: The lowest point of the parabola. - **Y-Intercept**: The point where the graph crosses the y-axis. - **Symmetry**: The graph is symmetric with respect to its vertex. 2. **Graph 2 (Top Right) - First Derivative: \( y = f'(x) \)** - **Description**: This graph shows the first derivative of the original function \( f(x) \). It is a straight line with a positive slope. - **Key Features**: - **Linearity**: Since the first derivative of a parabola (a quadratic function) is a linear function, the graph is a straight line. - **Slope**: Indicates the rate of change of the original function \( f(x) \). 3. **Graph 3 (Bottom Left) - Function: \( y = f(x) \) with Discontinuities** - **Description**: This graph represents another form of the function \( f(x) \) with abrupt changes (discontinuities) in the curve. - **Key Features**: - **Discontinuities**: Sudden jumps or drops in the function indicate points where the function is not continuous. - **Plateaus and Drops**: Portions where the graph changes height suddenly but remains constant over certain intervals. 4. **Graph 4 (Bottom Right) - Second Derivative: \( y = f''(x) \)** - **Description**: This graph illustrates the second derivative of the original function \( f(x) \). It is a piecewise linear function with positive and negative regions. - **Key Features**: - **Concavity**: The second
