Question

Explain how to use a graph of the function f(x) to
find f(3).

To find f(3) using a graph of the function f(x), locate the point on the graph where x = 3. Once you have found this point, look at the corresponding y-coordinate. This y-coordinate is the value of f(3).
Sample Response: For f(3), the input is 3 and you are looking for the output. To determine the function's value when x = 3, go to the value of 3 on the x-axis and then locate the graph for that value of x. Determine the value of y from the y-axis at that location on the graph.
