Question

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

Answer 1

Given a function f(x), the value of x is the x-coordinate on the x-axis. Therefore, if we wanted to find f(3) given the graph of f(x), we look for the point on the graph where x = 3, then find its y-value. That y-value is the answer to f(3).

This also applies for any other value of x.

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.
