Final answer:
The exponential function represented by the graph is f(x) = 6(3).
Step-by-step explanation:
The graph represents an exponential function. To determine the correct function, we need to identify the base of the exponential function. In this case, the base can be found by observing the value where the graph intersects the y-axis. The graph intersects the y-axis at 6, which means the base is 6. Therefore, the correct exponential function represented by the graph is f(x) = 6(3).
