Define end behavior of a function
The end behavior of a graph describes what happens to the values of \(y\) (the function values) as \(x\) approaches positive infinity (\(x \to \infty\)) and negative infinity (\(x \to -\infty\)). In simple terms, it describes what the ends of the graph are doing as you move far to the left and far to the right.
Evaluate the given options
- Telling where the graph is increasing or decreasing: This describes intervals of increase and decrease, which occur in the middle domain of the function, not the extreme ends.
- Telling what the ends of the graph is doing: This directly matches the definition of end behavior (how the graph behaves at its far left and far right limits).
- The highest point of the graph: This describes the absolute maximum of the graph.
- The lowest point of the graph: This describes the absolute minimum of the graph.
