Question

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

Answer 1

Answer: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.
