To use the graph to find the following:
A. To find f(3), locate x = 3 on the graph's x-axis and find the corresponding point on the y-axis. The y-coordinate of that point is the value of f(3).
B. To find the domain, look at the x-axis of the graph. The domain consists of all the x-values for which there are corresponding points on the graph.
C. To find any x-values for which f(x) = 2, look for points on the graph where the y-coordinate (height) is equal to 2. The corresponding x-coordinates (horizontal positions) of those points are the x-values for which f(x) = 2.
D. To find the range, examine the y-axis of the graph. The range consists of all the y-values for which there are corresponding points on the graph.
By looking at the graph and using these guidelines, you can find the answers to the questions.
