use this graph of f to find f(3).

Explanation:

Step1: Locate x - value on graph

Locate x = 3 on the x - axis.

Step2: Find corresponding y - value

Draw a vertical line from x = 3 until it intersects the graph of the function f. Then draw a horizontal line from the intersection point to the y - axis. The y - value at the intersection with the y - axis is the value of f(3). From the graph, when x = 3, y = 5.
