Question

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

Answer 1

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.
