What did you include in your response? Check all that apply.

A
For f(3), the input is 3 and you are looking for the output.
B
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.
C
Determine the value of y from the y-axis at that location on the graph.
