Analyzing Function Graphs

1. Define x-intercept and y-intercept. Explain how they can be useful in understanding a real-world scenario represented by a graph.

2. Describe what it means for a function to be increasing or decreasing. How is this visually represented on a graph, and what real-world information can you infer from these trends?

3. Explain the difference between a relative maximum and a relative minimum on a graph. Provide an example of a real-world scenario where identifying these points would be important.
