Question

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

Answer 1

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.

Step-by-step explanation:

Answer 2

A function is the relationship between the input (x) and the output variables (y). To find f(3) on a graph, we simply identify the corresponding y value where $x = 3$

Assume the graph of f(x) exists (see attachment).

The value of f(x) is the corresponding y value for the value of x.

Take for instance,

From the attached graph

$f(3) = 4$

The value is gotten by tracing the point where $x = 3$ on the y-axis.
