Answer:

D. 8

Explanation:

Using the graph of the function above, f(4) can be easily determined by tracing the corresponding coordinate of x = 4. When x = 4, on the x-axis, y = 8 on the y-axis.

The value of f(4), simply means, what is the value of y when x = 4.

Thus, the value of f(4) = 8.

The right answer is D. 8.
