Final answer:
To determine where a graph is increasing, you can analyze the slope using methods like the derivative test or visually examining the graph.
Step-by-step explanation:
To determine where a graph is increasing, we can analyze the slope of the graph. The slope represents how steep the graph is at each point. If the slope is positive, it means the graph is increasing. One method to analyze the slope is by using the derivative test, which involves finding the derivative of the function represented by the graph. Another method is to visually examine the graph and identify where it is getting steeper. For example, if line A is steeper than line B, then line A is increasing.
