find the value of f(5).

Explanation:

Step1: Locate x = 5 on x - axis

Find the point x = 5 on the horizontal x - axis.

Step2: Determine corresponding y - value

Go vertically from x = 5 until you hit the graph of y = f(x). Then go horizontally to the y - axis to read the y - value. From the graph, when x = 5, y = 5.

Answer:

5
