Question

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

Answer 1

Look at the graph at which x=3, then look and see what value y is and that will give you f(3).

Answer 2

Answer:

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.
