1. Put your pointer on "A", in blue, and click on it.
2. Use the left, right, up, down arrow to move the point, A.
3. From the graph can you tell me the relationship between the blue graph and red graph?
4. What is domain and range of blue graph and what is domain and range of red graph?
5. From 4, what can you conclude?

Question:
1. If the graph of a function is located on the first quadrant (QI), where is the graph of its inverse?
2. If the graph of a function is located on the second quadrant (QII), where is the graph of its inverse?
3. If the graph of a function is located on the third quadrant (QIII), where is the graph of its inverse?
4. If the graph of a function is located on the fourth quadrant (QIV), where is the graph of its inverse?
