While on vacation, Jorge and Jackie traveled to Bryce Canyon National Park in Utah. They were impressed by the differing elevations at the viewpoints along the road. The graph describes the elevations for several viewpoints in terms of the time since they entered the park. The graph represents a function E(t). Describe why the graph represents a function. Identify the domain and range of the function. Is this discrete or continuous data? Explain.
What is the y-intercept? Interpret the meaning of the y-intercept in the context of the problem.
a. Identify a relative maximum of the function represented by the graph.
b. What is the absolute maximum of the function represented by the graph? What does it represent?
a. Identify a relative minimum of the function represented by the graph.
b. What is the absolute minimum of the function represented by the graph? What does it represent?
