Student A and student B were given the following graph and asked to find the value of f(x) when x = 1. Student A gave an answer of 0 while student B gave an answer of −6. Who is incorrect? Drag and drop the correct option into each box to complete the explanation of the error.
 

 
Student  is incorrect. The student started at  on the y-axis, did not need to move horizontally to get to the graph, and so moved  to  on the x-axis. The student should have started at  on the x-axis, moved  to the graph, and then moved  to  on the y-axis, which is what student  did.


In this case, Student A is incorrect. Here's the full explanation:

**Student A** is incorrect. The student started at **0** on the y-axis, did not need to move horizontally to get to the graph, and so moved **down** to **−6** on the x-axis. The student should have started at **1** on the x-axis, moved **down** to the graph, and then moved **horizontally** to **−6** on the y-axis, which is what **Student B** did.

Let me know if you'd like more details or clarifications! Here are 5 related questions that can expand your understanding:

1. How do you interpret a point on a graph for a function \( f(x) \)?
2. What is the process of reading function values from a graph?
3. What is the difference between reading \( f(x) \) values on the y-axis and x-axis?
4. How can we use the slope of the graph to help interpret function values?
5. What types of errors are commonly made when interpreting graphs?

**Tip:** Always ensure you're reading the x-coordinate first when finding \( f(x) \) values from a graph.
