Evaluating Functions

Explain how to use a graph of the function f(x) to find f(3). Explain how to use a graph of the function f(x) to find f(3). For f(3), The input is 3 and you are looking for the output. To determine the functions 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. 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. What did you include in your response? Check all that apply. 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 a point on the graph for that value of x. Determine the value of y from the y-axis at that location on the graph.

Answer 1. Explain how to use a graph of the function f(x) to find f(3). For f(3), The input is 3 and you are looking for the output. To determine the functions 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. Answer 2. 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 a point on the graph for that value of x.
